Synthesis, Spectroscopic, and Magnetic Properties of Some Transition Metal Complexes with 4‐(2‐Pyridyl)‐1‐(diacetylmonoxime)‐3‐thiosemicarbazide

Cr(III), Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), Pd(II) and dioxouranium(VI), (UO2 2 +), complexes of 4‐(2‐pyridyl)‐1‐diacetylmonoxime‐3‐thiosemicarbazone (H2DMPT) have been synthesized and characterized by elemental analyses, molar conductance, spectral (IR, visible and NMR) and magnetic moment measurements. IR spectral data show that the ligand behaves in a bi, tri, and/or tetradentate manner. An octahedral structure is proposed for [Cr(HDMPT)Cl2(H2O)], [Mn(H2DMPT)Cl2(H2O)], [Ni(H2DMPT)Cl2(H2O)] and [Ni(HDMPT)(OAc)(H2O)2] while a square‐planar structure is suggested for [Pd(HDMPT)2], [Cu2(DMPT)Cl2(H2O)]·H2O and [Co(DMPT)2].
