Synthesis and Characterization of Rhodium (III), Iridium(III), Palladium(II) and Platinum(II) Complexes of Cyclohexanone Thiosemicarbazone

Abstract

A series of cyclohexanone thiosemicarbazone complexes of the general compositions, M(ligand)₃X₃ and M(ligand-H)₃, M = Rh(III), Ir(III), × = Cl, Br or I and M(ligand)₂X₂ and M(ligand-H)₂, M = Pd(II) and Pt(II), × = Cl, Br and I, have been prepared and characterized by elemental analysis, conductivity Measurements, magnetic susceptibility measurements, infrared and electronic spectral studies. Complexes of rhodium(III) and iridium(III) are six-coordinate octahedral while the complexes of palladium(II) and platinum(II) are square planar.
