Abstract The fine and hyperfine structure of two dinuclear sulfide bridged Fe−Mo complex anions and their W homologues have been studied by magnetic susceptibility and Mössbauer measurements. It is shown that, by following a stepwise methodology, it is possible to derive from the low temperature magnetization data the value and sign of the fine structure parametersD andE/D. These parameters are further confirmed by an independent analysis of the Mössbauer data. Magnetic and electric hyperfine interaction parameters are also determined from the Mössbauer results. Both fine and hyperfine parameters point to a valence scheme, for all complexes, of FeII−MoVI(WVI) with a varying degree of charge delocalization from the iron to the molybdenum (tungsten) site. The parameterD is negative with an orientation of itsz axis close to theV zz axis.
