Abstract

New coordination compounds of iron(II) trifluoromethylsulfonate, perrhenate, and tetraphenylborate with tris(pyrazol-1-yl)methane (HC(Pz) 3) of the composition [Fe(HC(Pz)3)2]A 2 (A = CF3SO3 - (I), ReO4 - (II), and B(C6H5)4 - (III)) were synthesized and studied by the method of static magnetic susceptibility and IR and electronic spectroscopies. The crystal and molecular structures of compounds I and II were determined by X-ray diffraction analysis. The magnetochemical study of complexes I-III in the interval from 275 to 500 K showed that they possessed the high-temperature spin transition 1 A 15 T 2 accompanied by thermochromism.
