Complexes of the type [M(DMPS)2X2]. Where M=cobalt(II) nickel(II) and copper(II) DMPS =2-6 Dimethyl 4 pyrone semicarbazone and X = CI-, Br-, I-, NO3- and CIO4- have been prepared, the ligand and complex have been characterized by elemental analysis IR spectra, electronic spectra, molar mass, conductance, magnetic susceptibility values. DMPS acts as neutral bidentate ligand and coordinate is proposed through azomethine N and carbonyl oxygen atoms of semicarbazone moiety the remaining position of metal ions are satisfied by negative anions such CI, Br, I, NO3 or CIO4 the complexes were proposed to be monomeric octahedral in geometry.
