Abstract
The frozen-solution Mossbauer spectra of salts containing the anion [F e4S4(SBut)4]2- show relatively constant isomer shifts. In a range of s olvents, at the concentrations studied, there is no simple dependence of the quadrupole splitting (q.s.) on either catin or solvent. The tot al range of q.s. observed in these solvents is greater the smaller the cation. In the solvents acetonitrile and dimethyl sulphoxide the tetr amethylammonium salt exhibits anomalous q.s. values. A comparison is m ade with the variation of q.s. with cation in the solid state.
