Abstract: | Several complexes of 5,8-diethyl-7-hydroxy-6-dodecanone oxime [H2L] with Cu(II) and Ni(II) have been synthesized and characterized by means of a number of techniques including elemental analysis, IR spectra, magnetic susceptibility measurements, electronic absorption spectra, NMR spectra, and mass spectra. The results indicate that Cu(II) and Ni(II) generally form analogous, isomorphous complexes, although no bis-[H2L] complex with Cu(II) has been isolated. [Cu(L)]n and [Ni(L)]n are oligomeric complexes with pseudo-octahedral geometry. [Ni(HL)2] is cis-square-planar (C2ν) with bifurcated hydrogen bridges. [Ni(H2L)3SO4] and [Cu(H2L)3SO4] have octahedral symmetry in which the sulphate is coordinated as a unidentate ligand and the oxime is functioning as a neutral ligand. |
