摘要：

New iron(II) complexes with 2,6-bis(1H-imidazol-2-yl)-4-methoxypyridine (L) of the composition [FeL2]A(n)& BULL;mH(2)O (A = SO42-, n = 1, m = 2 (I); A = ReO4-, n = 2, m = 1 (II); A = Br-, n = 2, m = 2 (III)) have been synthesized and investigated. To determine the coordination ability of the ligand, a single crystal of a copper(II) complex of the composition [CuLCl2] (IV) was obtained and studied by X-ray technique. Compounds I-III were studied using methods of X-ray phase analysis, electron (diffuse reflection spectra), infrared and Mossbauer spectroscopy, static magnetic susceptibility. The study of the & mu;(eff)(T) dependence showed that the (1)A(1) & LRARR; T-5(2) spin crossover manifests itself in the compounds. The spin crossover is accompanied by thermochromism: there is a distinct color change orange & LRARR; red-violet.
