Abstract
A cubane-type cluster (Et4N) [VFe3S4(Et(2)dtc)(4)] has been synthesize d from a self-assembly reaction system VS43-/FeCl2/Et(2)dtc(-)/PhS- in acetonitrile (Et(2)dtc(-) = diethyldithiocarbamate). The compound has been structurally characterized by X-ray crystallography. Mossbauer a nd structural parameters have been used to deduce the oxidation states of the metal atoms in [VFe3S4](3+) core indicating that there are thr ee Fe atoms with mean oxidation state of ca +2.8. Proton NMR spectrum indicates the paramagneticity of the cluster. The chemical shift of V- 51 NMR was observed at -210 ppm. Variable-temperature magnetic suscept ibility measurement reveals an antiferromagnetic interaction in the VF e3 coupling system. (C) 1997 Elsevier Science Ltd.
