X-ray K-absorption near edge studies have been carried out onthe binuclear copper (II) dithiocarbamate (dtc) complexes having the following general structure. It has been found that the chemical shift values are higher in the chlorine adducts as compared to the values of chemical shift reported by us in an earlier work for the parent complexes, showing that the chlorine adducts are more ionic. The observed splitting of the principal absorption maximum (1s -> 4p) in the chlorine adducts has been explained in terms of the splitting of the metal 4p orbital degeneracy.
