Abstract

A number of dioxouranium(VI) complexes of some monobasic biden- tate dithiocarbamate(dtc) ligands have been synthesized. Monobasic bidentate dithiocarbamate ligands were prepared by the reaction of 1:1 molar ratio of ethylenediamine, N,N-dimethylethylenediamine, N,N-diethylethylenediamine, 1,3-propanediamine, N,N-dibutyl-tri-methylenediamine, 1,6-hexanediamine with carbondisulphide. Physico-chemical analytical, e.g. elemental analysis, IR Spectral data suggest the formation of (UO 2 L 2 ) type complexes. The molar conductance values obtained for a number of complexes indicate the non-elec- trolytic nature of the complexes. The magnetic and electronic spectral studies of the prepared complexes indicate the presence of the 5f 0 6d 0 7s 0 electronic configuration characteristic of the 6+ oxidation state of uranium.
