The complexes of the type ML2 (SCN)2 have been synthesised from M (SCN)2 [M=CO(II), Ni(II)] and N-substituted thioureas (L) such as chlorophenyl (Cl-Ptu), tolyl (totu), methoxy phenyl (meo-ptu), nitrophenyl (NO2-Ptu) and bromophenyl (Br-Ptu) thioureas. All the complexes are non-electrolytes in acetone.ir spectral studies reveal that thiourea and thiocyanate are bonded to the central metal through S and N respectively. Magnetic susceptibility studies at room temperature (25°C) and electronic spectral data confer octahedral symmetry to nickel (II) and tetrahedral symmetry to cobalt (II) complexes.
