Bis[dihydrobis(pyrazol-1-yl-κN2)borato]bis(methanol-κO)iron(II)

Abstract

The structure determination was undertaken as part of a project on the synthesis of new spin-crossover compounds based on octahedral FeII bis(pyrazolyl)borate complexes. The asymmetric unit of the title compound, [Fe(H2B(pz)2)2(CH3OH)2] [H2B(pz)2 = dihydrobis(pyrazol-1-yl)borate, C6H8BN4], consists of one FeII cation that is located on a centre of inversion, as well as one methanol molecule and one H2B(pz)2 dianion that occupy general positions. In the crystal, the FeII cations are coordinated by two methanol molecules and four N atoms of two H2B(pz)2 anions within a slightly distorted octahedron. Bond lengths and angles between the FeII atom and the H2B(pz)2 anion are comparable to those in related FeII complexes.
