Abstract

The salts [Fe(C₅Me₅)₂][M(C₂B₉H₁₁)₂)], (M = Cr, Fe, Ni), have been prepared by metathesis of [Fe(C₅Me₅)₂]Cl and [(CH₃)₄N][M(C₂B₉H₁₁)₂], (M = Cr, Fe, Ni), and the three salts have been shown to be isostructural from powder X-ray diffraction studies. The structure of the salt [Fe(C₅Me₅)₂][Fe(C₂B₉H₁₁)₂)] has been determined by a single crystal X-ray diffraction study.The anions and cations pack in a distorted CsCl-type structure in which the distortion is thought to arise from the non-spherical shape of the [Fe(C₂B₉H₁₁)₂)]^- anion.The solid-state magnetic susceptibility data for all three salts can be fitted to the Curie-Weiss law between 6 and 296 K. Low values of ? indicate there are no significant ferromagnetic or antiferromagnetic interactions between the unpaired spins, even at low temperatures. © 1994.
