Abstract
Methods are developed for preparing iron(II) complexes with tris(3,5-dimethylpyrazol-1-yl)methane {HC(3,5-dmpz)3} and closo-borate(2-) ions, namely [Fe{HC(3,5-dmpz)3}2]B10H10 · H2O (I) and [Fe{HC(3,5-dmpz)3}2]B12H12 · H2O (II). These complexes were characterized by static magnetic susceptibility measurements (2–325 K), electronic spectroscopy (diffuse reflectance spectra), and IR spectroscopy. The complexes have a distorted octahedral geometry of the coordination polyhedron; the coordination core is FeN6. μeff(T) studies show low-temperature incomplete spin crossover in complex I and antiferromagnetic exchange coupling among iron(II) unpaired electrons at temperatures below 90 K in complex II. Complex I shows thermochromism; the color transition upon cooling is white ↔ pink.
