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 Nano cadmium(II)-benzyl benzothiazol-2-ylcarbamodithioate complexes: Synthesis, characterization, anti-cancer and antibacterial studies.Name: 1,10-Phenanthroline.
Benzyl benzothiazol-2-ylcarbamodithioate (BBCT) was used as a ligand for the synthesis of [Cd(BBCT)(PPh3)Cl]Cl (1), [Cd2(BBCT)2(μ-dppm)2]Cl4 (2), or [Cd(BBCT)(phosphine)]Cl2 (where phosphine is dppe (3), dppp (4), dppb (5)) and [Cd(BBCT)(amine)]Cl2 (where amine is bipy (6) or phen (7)). The characterizations (molar conductivity, elemental anal., IR spectra and 31P NMR, 1H NMR and 13C NMR spectra) prove that BBCT ligand behaves as a bidentate ligand through the N atom of thiazole ring group and S atom of thion group while the phosphines or amines ligands behave as bidentate ligand through the P atoms or N atoms, resp. Furthermore, the nanostructure of (1) and (7) was examined by SEM and the results demonstrate the presence of regular nanostructures. The complex (1) shows fiber-grip-like geometry with 85-110 nm while complex (7) shows spiny-flowers-like nanostructures with the flower-forming spines within the range of 80-190 nm. The antibacterial activity of the complexes (1, 2, 3, 6, 7) against S.Epidermidis, S. aureus (gram-pos.) and C.Freundii (gram-neg.) was examined using amikacin as a pos. control. However, all the complexes showed a high ability to inhibit the bacterial species studied, and the inhibition zone was better than that obtained with amikacin. Moreover, the anti-cancer activity of the complexes (1) and (7) against ovarian cancer cell was studied and the results show that both complexes gave cell viability values less than 6%.
