The ligand behaves as a neutral bidentate in coordination. This coordination takes place via the carbonyl oxygen of (C=O) and nitrogen atom of the N(2)H group in all complexes. A new series of Copper(II), Nickel(II), Cobalt(II) and Lithium(I) complexes of 2- (phenylaminoactetyl-N-phenyl hydrazine carbothioamide(H2L) were prepared and characterized by IR, elemental analysis, H NMR spectroscopy, magnetic susceptibilities, electronic spectra and antibacterial activity. Results showed that these medically important complexes had positive effects against some pathogenic bacteria including gram positive bacteria and gram negative bacteria that are pathogenic to human and animals.
