In this study, two types of tetra- and hexa-coordinate complexes were prepared, derived from prolinedithiocabamate ligand, ligand adducts phenathroline, and metal ions to give the general formula[M(proldtc)2], [M(proldtc)2phen], M= Ni (II), Cu (II), Zn (II), Cd (II) and Hg (II), The dithiocarbamate complexes were identified by electronic (UV-visible), infrared (FT-IR), magnetic susceptibility and nuclear magnetic resonance (NMR) spectra, surface study through electron microscopy and molar conductivity, which confirmed that all complexes are non-electrolytic. The tetra coordinate complexes of (Ni (II), Cu (II)) have a square planar and tetrahedral structure for (Zn (II), Cd (II) and Hg (II)). The other [M(proldtc)2phen] complexes with octahedral structure. SEM showed that the complexes show agglomerated morphological structure. The in vitro biological activity of the ligand and its complexes were tested in inhibiting the growth of bacteria against two types of bacteria: Escherichia coli, and Staphylococcus aureus.
