title: Metal complexes derived from hydrazoneoxime ligands: V. Spectral and structural studies on diacetylmonoxime n-alkanoylhydrazones and their nickel(II) and copper(II) complexes.
abstract: A series of diacetylmonoxime n-alkanoylhydrazones (H₂L(n), n=4, 5, 6, 12 and 16) were prepared by the condensation of diacetylmonoxime with the corresponding n-alkanoylhydrazine in ethanol. The X-ray crystal structure of diacetylmonoxime octadecanoyl hydrazone has been solved and its molecular and supramolecular structures have been discussed. Both neutral dinuclear Cu(II) and Ni(II) complexes, [{M(L(n))}₂] (M=Cu, Ni and n=4, 5, 6, 12 and 16) as well as cationic dinuclear Cu(II) complexes, [Cu₂(L(n))(HL(n))]NO₃ (n=12 and 16) have been also prepared and characterized by elemental analyses, FD- and ESI-mass spectra as well as IR, UV-Vis, (1)H NMR, (13)C NMR spectra. Variable temperature magnetic susceptibility measurements for dinuclear Cu(II) complexes have been also discussed.
