description Novel iron(II) coordination compounds containing a ligand 2,6-bis(1H-imidazol-2-yl)pyridine (L), having such a composition as [FeL(2)]SO(4)·0.5H(2)O, [FeL(2)]Br(2)·H(2)O, [FeL(2)](ReO(4))(2), [FeL(2)]B(10)H(10)∙H(2)O, [FeL(2)]B(12)H(12)∙1.5H(2)O had been synthesized and studied using UV-Vis (diffuse reflectance), infrared, extended X-ray absorption fine structure (EXAFS), and Mössbauer spectroscopy methods, as well as X-ray diffraction and static magnetic susceptibility methods. The analysis of the μ(eff)(T) dependence in the temperature range of 80–600 K have shown that all the obtained complexes exhibit a high-temperature spin crossover (1)A(1) ↔ (5)T(2).
