Synthesis, Characterization and Biological Activities of Cu(II), Ni(II), Zn(II), Cd(II), Sn(II), Co(II), Sb(III) and Fe(III) Complexes with Schiff base Methyl 3-[(E,E)-3-phenylprop-2-enylidene]dithiocarbazate
The Complexes of Cu(II), Ni(II)), Zn(II), Cd(II), Sn(II), Co(II), Sb(III) and Fe(III) with Methyl 3-[(E,E)-3-phenylprop-2- enylidene]dithiocarbazate have been synthesized and characterized by elemental analysis, molar conductance, magnetic susceptibility, FT-IR, UV-Visible spectroscopy. The Schiff bases in every case behaved as bidentate, uninegative ligands. The complexes of Cu(II), Co(II) and Fe(III) are paramagnetic while all other complexes are diamagnetic. The complexes [Cu(C11H11N2S2)2] and [Ni(C11H11N2S2)2] had, square planar structures with two ligands satisfying the four steriochemical sites, where the complexes [Zn(C11H11N2S2)2] and [Cd(C11H11N2S2)2] were tetrahedral and the complexes [Sn(C11H11N2S2)2(H2O)2], [Co(C11H11N2S2)2(H2O)2], [Sb(C11H11N2S2)2(NO3) (H2O)] and [Fe(C11H11N2S2)2(NO3)(H2O)] were octahedral in geometry. The metal complexes have been screened for their antibacterial activity.
