|Title:||Synthesis and characterization of copper(I) tetrathiomolybdates|
Nagaraja, K S

|Abstract:||A few copper(I) complexes with tetrathiomolybdates of the type A [CuO,MoS4] [where A isethylenediammonium (0.5enH2), hydrazinium (0.5-N2H6)', dimethylammonium, piperidinium, pyrrolidinium, morpholinium, tetraethylammonium, tetrabutylammonium and tetraphenylphosphonium] have been prepared and characterized. The magnetic and EPR results indicate that copper and molybdenum are in + 1 and +6 oxidation states respectively. The infrared spectral results suggest the tetradentate nature of MoS . The cathodic peak potential observed at - 0.90V SCE for (NEt4)[Cu MoS] in cyclic voltammogram is assigned to the reduction of copper(I) to copper(O). The reaction of replacement of the ligand from Cu(Et2dtc)2 by MoS followed by the reduction of Cu(II) to Cu(I), giving [CuMoS4]-- reveals that MoS can act as a potential antagonist to copper.|
