Preparation and characterization of cadmium [II] keto-stabilized phosphonium or sulfonium complexes

ABSTRACT

Two new sets of cadmium complexes were prepared from the reaction of phosphonium or sulfonium salts with cadmium chloride. The complexes have the general formulae [CdL Cl2] and [CdL2] Cl2 and were characterized by elemental analysis and conductance measurements. The IR spectra of the complexes showed that the CO group of the phosphonium or sulfonium salts coordinates to the central Cd [II] ion. Electronic spectra used to study the spatial distribution of the ligands around the central cadmium [II] ion
