Abstract
Synthesis procedures for new coordination compounds of iron(II) with tris(pyrazol-1-yl)methane (HC(pz)3), containing cluster anions in the outer sphere, of the composition [Fe{HC(pz)3}2][Mo6Cl14]•2H2O (I), [Fe{HC(pz)3}2][Mo6Br14]•H2O (II), and [Fe{HC(pz)3}2]2[Re6S8(CN)6]•2H2O (III) are developed. The compounds are studied by static magnetic susceptibility, electronic, IR, and Mössbauer spectroscopic methods. The magnetochemical study shows that in the polycrystalline phases of all compounds the spincrossover 1 А 1 ⇔ 5 Т 2 is observed which is accompanied by thermochromism.
