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.
