Abstract

G. Krishnan and S. suprabha

Some novel metal complexes of nickel (II) derived from N-amidino-N1-naphthylthiourea (NPTU) have been synthesized and characterized by elemental analysis, molar conductance and spectral studies. The ligand behaves as neutral bidentate and coordinates through sulphur and nitrogen. Complexes are ascertained the general formula {Ni(NPTU)2X2] (X = Cl–, Br–, ClO–4, NO–3, NCS–). Thermal behaviour of [Ni(NPTU)2(NO3)2] was determined. Ligand and metal complexes were screened for their antibacterial and antitubercular activities.
