Abstract

300-303Heterobinuclear complexes [MnMoO2 (L)4.(H2O)] and (HgMoO2 (L)3, (H2O)] (L- diethyldithiocarbamate, 4-morpholinyldithiocarbamate, 1-piperidinyldithiocarbamate) have been prepared and characterized. The magnetic moment, EPR and PES spectral data suggest the presence of manganese(III) or mercury(II) with molybdenum(V) in the complexes. The 1H and 13C NMR chemical shifts of the complexes indicate the presence of two types of dithiocarbamates coordinated to molybdenum and a heterometal atom. The redox behaviour of the complexes are discussed from CVM data. The proposed structure consists of an octahedral manganese(III) or mercury(ll) and distorted octahedral molybdenum( V) bridged by an oxo group
