Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Inorganic Chemistry called MIIIDyIII3 (M = FeIII, CoIII) Complexes: Three-Blade Propellers Exhibiting Slow Relaxation of Magnetization, Author is Xu, Gong-Feng; Gamez, Patrick; Tang, Jinkui; Clerac, Rodolphe; Guo, Yun-Nan; Guo, Yang, which mentions a compound: 18583-60-3, SMILESS is [BH-](N1N=CC=C1)(N2N=CC=C2)N3N=CC=C3.[K+], Molecular C9H10BKN6, Electric Literature of C9H10BKN6.

[DyIII(HBpz3)2]2+ moieties (HBpz3- = hydrotris(pyrazolyl)borate) and a 3d transition-metal ion (FeIII or CoIII) were rationally assembled using a dithiooxalato dianion ligand into 3d-4f [MDy3(HBpz3)6(dto)3]·4MeCN·2CH2Cl2 [M = Fe (1), Co (2)] complexes. Single-crystal x-ray studies reveal that three eight-coordinated DyIII centers in a square antiprismatic coordination environment are connecting to a central octahedral trivalent Fe or Co ion forming a propeller-type complex. The dynamics of the magnetization in the two isostructural compounds, modulated by the nature of the central MIII metal ion, are remarkably different despite their analogous d.c. magnetic properties. The slow relaxation of the magnetization observed for 2 mainly originates from isolated Dy ions, since a diamagnetic CoIII metal ion links the magnetic DyIII ions. In the case of 1, the magnetic interaction between S = 1/2 FeIII ion and the three DyIII magnetic centers, although weak, generates a complex energy spectrum of magnetic states with low-lying excited states that induce a smaller energy gap than for 2 and thus a faster relaxation of the magnetization.

As far as I know, this compound(18583-60-3)Electric Literature of C9H10BKN6 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

In the presence of N-methylpyrazole (N-CH3pz), similar reaction procedures gave [MCl(BHpz3)2(N-CH3pz)], of which further treatment with Na 8-quinolinolate Na(quin) afforded the stable complexes [M(BHpz3)2(quin)] quant.
