The synthesis and characterization of complexes of Co(II), Cu(II), Ni(II), Hg(II),Mn(II), Cd(II), Pd(II) and UO2(VI) with thiophene-2-carboxaldhyde phenoxyacetyl hydrazone (HTCPA) (Structure 1) are reported. Elemental analyses, molar conductivities, magnetic measurements and spectral (IR and visible) studies have been used to elucidate their structure. The IR show that (HTCPA) behaves as neutral or mononegative bidentate ligand. Different stereochemistries are proposed for each of the Co(II), Cu(II), Ni(II) and Mn(II) complexes on the basis of spectral and magnetic studies.
