Abstract The synthesis of new complexes of Ni(II), Co(II), Cu(II), Zn(II), Cd(II) and Hg(II) with thiosemicarbazones derived from 4-benzamidothiosemicarbazide and 4-acetylpyridine (BACPT) or 3-pyridine aldehyde (BPAT) are reported. These complexes have been characterized by elemental analyses, molar conductivities, magnetic moments and spectral (visible, u.v., i.r.) studies. I.R. spectra show that BPAT acts as a monovalent or neutral bidentate ligand while BACPT behaves in a monovalent bidentate, tridentate and neutral tetradentate manner. The magnetic and electronic spectral data confirmed that the copper complexes of BACPT are diamagnetic while that of BPAT is paramagnetic, the Co(II) complex of BACPT has an octahedral structure while that of BPAT has a tetrahedral structure and the Ni(II) complexes of both ligands have octahedral structures. The molar conductivities for all complexes are reported in the range of non-electrolytes except that of the copper complex of BPAT which suggest that it is a 1:1 electrolyte.
