Abstract
The magnetic susceptibility of tris(pyrrolidine-1-carbodithioato)iron(III) and the tris(diethyldithiocarbamato) derivatives of chromium(III), manganese(III) and iron(III) were measured down to temperatures of 4·2 K and below. The susceptibilities are independent of the strength of the magnetic field. The magnetic moments of the chromium and manganese compounds are essentially independent of temperature and near the spin-only value. The moment of Fe(Et2dtc)3 falls from 2·10 to 1·85 B.M. between 83 and 4·2 K. This behaviour is interpreted in terms of a low-symmetry splitting of the 2T2g term. The magnetic susceptibility of tris(pyrrolidine-1-carbodithioato)iron(III) became almost constant below 3 K, and cannot be accounted for on the basis of the zero-field splitting of the 6A1g ground term suggested by other studies.Keywords
