Description 745-752
A new aroylhydrazone ligand, di-2-pyridyl ketone-4-methoxybenzhydrazone (DKMBH∙H2O) and its three complexes
with cobalt(II), copper(II) and zinc(II), labelled Co(DKMB)Cl (1), Cu(DKMB)Cl (2), and Zn(DKMB)Cl (3) have been
prepared and structurally studied. The spectroscopic techniques like IR, UV-Vis, MS, and 1H NMR, as well as CHN
analysis and thermal analysis, have been used to physico-chemically characterize the synthesized compounds. The IR and
1H NMR analyses have made clear that the aroylhydrazone remains in the amido form in the solid state. The IR spectral
measurements further support the tridentate character of the NNO donor aroylhydrazone. In all complexes, pyridine
nitrogen, azomethine nitrogen, and iminolate oxygen of the tridentate aroylhydrazone are involved to coordinate to the
metal centre.
