OXOVANADIUM(4) COMPLEXES OF DITHIOCARBAMATES

Complexes of oxovanadium(IV) with 5 N,N-disubstituted dithiocarbamates (dtc) have been prepared and characterized. The ligands are diethyl-, ethylphenyl-, piperidine-, methylcyclohexyl-, and dicyclohexyl-dithiocarbamate; and the general complex formula is VO(RR′ dtc)2. Vibrational, electronic and EPR spectral studies have been made and the effects which varying the R groups have on the VO, C|N and C|S stretching frequencies and on the electronic transitions are discussed in terms of the electronic structure of the dtc ligands and a qualitative molecular orbital scheme for the complexes. © 1969.
