Crystal structure of bis-{(3,5-di-methyl-pyrazol-1-yl)di-hydro-[3-(pyridin-2-yl)pyrazol-1-yl]-borato}iron(II).

ABSTRACT: The structure determination of [Fe(C₁₃H₁₅BN₅)₂] was undertaken as part of a project on the modification of the recently published spin-crossover (SCO) complex [Fe{H₂B(pz)(pypz)}₂] (pz = pyrazole, pypz = pyridyl-pyrazole). To this end, a new ligand was synthesized in which two additional methyl groups are present. Its reaction with iron tri-fluoro-methane-sulfonate led to a pure sample of the title compound, as proven by X-ray powder diffraction. The asymmetric unit consists of one complex mol-ecule in a general position. The Fe^II atom is coordinated by two tridentate N-binding {H₂B(3,5-(CH₃)₂-pz)(pypz)}^- ligands. The Fe-N bond lengths range between 2.1222 (13) and 2.3255
