“…The calculated orientation of Vii is in agreement with our experimental work on [Cl2FeS2MoS2f-, which is described in the following paper in this joumal. 41 From the correlation between measured isomer shift o and calculated charge density pea) at the iron nucleus we derive for the compounds studied here an isomer shift calibration constant a = -0.25 mm S-I, which is close to our values found for other iron-containing compounds (a ~ 0.2 mm S-I). From the trend of 0 and pea) values of the binuclear FeMoS systems with respect to the mononuclear FeS systems we conclude, that Moslis a charge-withdrawing ligand, which partially delocalizes charge from Fe3d AO's into the overlap region of Mo-S bonds.…”

“…We therefore carried out an extensive experimental test in order to determine the sign of ViZ and the orientation of ViZ. In the following paper within this journal 41 we describe our Mossbauer studies on single crystals of compound III, which indeed indicate that Viz is positive and oriented along the molecular x axis in full agreement with our calculated results.…”
