In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Slow relaxation of Dy(III) single-ion magnets dominated by the simultaneous binding of chelating ligands in low-symmetry ligand-fields, published in 2022, which mentions a compound: 66-71-7, mainly applied to dysprosium bipyridine phen salicylaldoxime complex preparation crystal structure magnetism, Name: 1,10-Phenanthroline.

Electronic effect and geometry distortion of low-symmetry ligand-field on the anisotropy barrier (Ueff) of spin reversal were compared in three Dy(III) single-ion magnets through the simultaneous binding of chelating ligands. The substitution of N,O-salicylaldoxime by N,N’-1,10-phenanthroline in the distorted triangular-dodecahedronal field sharply decreases the Ueff by 286 K due to an increase in nonpreferred transverse anisotropy, while the geometry distortion with CShM = 1.569 went down to 1.376 only lowering the Ueff by 12 K. The co-coordination strategy of heterodonor ligands highlights the importance of ligand-surroundings on the relaxation dynamics.

After consulting a lot of data, we found that this compound(66-71-7)Name: 1,10-Phenanthroline can be used in many types of reactions. And in most cases, this compound has more advantages.

Heterocyclic dithiocarbamate complex of manganese and the adducts of the complex with 1,10-phenanthroline and 2,2-bipyridyl resp. were synthesized and characterized. The complexes were used as single-source precursors for the preparation of MnS nanoparticles via thermolysis in oleylamine (OLA) and dodecanethiol (DT). The optimized reaction parameters have resulted in the formation of α-MnS and γ-MnS nanoparticles depending on the dispersion medium and the nature of the precursor. The same precursors were also used for the deposition of MnS thin films by the aerosol-assisted chem. vapor deposition (AACVD) method in varying solvents and temperatures The morphol. and phase of the synthesized nanoparticles were shown to be affected by the precursor type and the nature of the surfactants. SEM images showed that the morphol. of the deposited thin films is affected by precursor type and the deposition temperature Worm-like to rod-like films were observed on TEM images at 350 °C, which changes to spherical or cubic films at 450 °C. Magnetic measurements at room temperature showed the α-MnS and γ-MnS nanoparticles in paramagnetic states due to Mn2+ moments. The susceptibility for the γ-phase is at least double that of the α-phase. Finite and small hysteretic effects in low fields are indicative of small ordered antiferromagnetic phases due to neg. exchange interaction between Mn2+ ions.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Homo- and heterometallic oxalate-based complexes obtained using [Cr(C2O4)3]3- building block – Two polymorphs of a solvate, published in 2022-01-01, which mentions a compound: 66-71-7, Name is 1,10-Phenanthroline, Molecular C12H8N2, Safety of 1,10-Phenanthroline.

Two heterometallic complex salts, as polymorphs of a solvate, consisting of three different mononuclear units, [CuCl(phen)2][Cu(H2O)(phen)2][Cr(C2O4)3]·nH2O [n = 5 (1) and n = 8 (2); phen = 1,10-phenanthroline] were obtained in reactions in which [Cr(C2O4)3]3- was used as a building unit. The polymorphs of a solvate are obtained in crystalline forms that differ in type or stoichiometry of included solvent mols., mostly obtained under different conditions. In this [CuIICrIII] system, the used solvents and crystallization method influence the final product, i.e., the formation of a specific solvatomorph. From the reaction of an aqueous solution of K3[Cr(C2O4)3]·3H2O and acetonitrile solutions containing phen and CuCl2·2H2O, compound 1 was formed when the layering technique is used; and compound 2 can be obtained from the mixture of these reactants, but using methanol instead of acetonitrile. Based on the index parameter for the degree of trigonality, τ, the geometry of copper(II) atoms of the [Cu(H2O)(phen)2]2+ cations in 1 and 2 are distorted from square pyramidal toward trigonal bipyramidal conformation, while those of [CuCl(phen)2]+ have a trigonal bipyramidal geometry. Interestingly, in the presence of [NBu4]+ cations, and applying slow liquid diffusion, partial decomposition of the building block [Cr(C2O4)3]3- occurred and the homobinuclear oxalate-bridged complex [{Cu(bpy)Cl}2(μ-C2O4)]·CH3OH (3; bpy = 2,2′-bipyridine) was formed. Consequently, the oxalate ligand released from the coordination sphere of CrIII was coordinated to CuII ions during the crystallization process. The obtained oxalate-based compounds 1-3 were characterized by IR spectroscopy and single-crystal x-ray diffraction.

Let’s take a look at the latest research on this compound (cas:66-71-7).

Adaptive membranes that can intelligently control their permeability or selectivity depending on the surrounding environments are of extraordinary importance in the separation technol. area. Herein, we report the pH responsive membranes through covalently grafting weak Polyelectrolytes (poly(acrylic acid) (PAA) or poly(4-vinylpyridine) (P4VP)) onto the regular two dimensional (2D) channels stacked by Graphene oxide (GO) nanosheets. Attributed to the reversible shrinking/stretching function of PAA (or P4VP) chains with the variation of external pH, the switchable 2D GO channels are thus established successfully. Correspondingly, the resulting PAA@GO and P4VP@GO 2D membranes show promising nano-gating ratios of ∼ 5 accompanied by satisfactory water permeances. Furthermore, the pH responsive 2D channels render these two types of membranes with the adaptive ability of rejecting different sized species according to separation requirements. For disposing industrial alk. (or acid) effluents, PAA@GO (or P4VP@GO) membranes exhibit outstanding alk. (or acid) recovery performance as well.

Utilizing 1,10-phenanthroline-type bifunctional ligands, an efficient Cu-catalyzed intermol. site-selective remote C-H amination using cyclohexenone derivatives and anilines was realized. The amide group installed on the bifunctional ligand played a key role in stabilizing the N-centered radical generated in-situ to realize C-N-directed formation. Meanwhile, a useful catalytic system for site-selective intermol. remote γ-C-H amination to p-aminophenols and γ-aminated enones was established. This economical and practical approach using oxygen as the terminal oxidant was mild and environmentally friendly.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1,10-Phenanthroline, is researched, Molecular C12H8N2, CAS is 66-71-7, about Phenanthroline-based Ni(II) coordination compounds involving unconventional discrete fumarate-water-nitrate clusters and energetically significant cooperative ternary π-stacked assemblies: Antiproliferative evaluation and theoretical studies.Name: 1,10-Phenanthroline.

Two new Ni(II) coordination complexes involving fumarate and 1,10-phenanthroline viz.; [Ni2(phen)2(μ-fum)(H2O)6](fum)·6H2O (1) and [Ni(phen)2(H2O)2](0.5 fum)(NO3)·4H2O (2) (fum = fumarate, phen = 1,10-phenanthroline) were isolated in aqueous medium at room temperature Crystal structure analyses of the compounds reveal cooperative (π-π)2/(π-π)1/(π-π)2 stacked ternary assemblies which provide stabilities to the layered architectures. The lattice water and the large counteranions in the lattice of the compounds are involved in the formation of unconventional discrete cyclic fumarate-water, fumarate-water-nitrate clusters and infinite nitrate-water 1D chains that are very scarcely reported in the literature. The energetically significant π-stacked dimers observed in the biol. relevant ternary assemblies of the crystal structures were further studied theor. using DFT calculations and NCI plot index computational tools. DFT calculations reveal that the cooperative (π-π)2 binding mode of 1 is energetically more significant than (π-π)1 Moreover, the study also reveals that for the equivalent cooperative (π-π)1 stacking interactions in both the structures, the energy is unexpectedly higher for 2 than that observed for 1. Both the compounds induce significant cytotoxicity in Da’s lymphoma (DL) cancer cells by inducing apoptotic cell death with negligible cytotoxicity in normal cells. Decrease in the mitochondrial membrane potential (MMP) of DL cells after treatment with the compounds also corroborates the apoptotic cell death. The mol. docking and pharmacophore features reveal that the compounds interact and accommodated well with the active sites of anti-apoptotic proteins.
