Diagnostic features for the linkage isomerism of the oximato group: Characterization of some Cu(II), Co(II) and U(VI) complexes of a dioxime schiff-base ligand

The reactions of the dioxime ligand N, N'-ethylenebis(isonitrosoacetylacetoneimine) with Cu(II), Co(II) and U(VI) ions produced metal complexes with the oximato groups coordinated through both oxygens, both nitrogens or one oxygen and one nitrogen. Some interconversion of isomers was observed....

More Information
Summary:The reactions of the dioxime ligand N, N'-ethylenebis(isonitrosoacetylacetoneimine) with Cu(II), Co(II) and U(VI) ions produced metal complexes with the oximato groups coordinated through both oxygens, both nitrogens or one oxygen and one nitrogen. Some interconversion of isomers was observed. The U(VI) complexes reacted with Ni(II) acetate to produce the Ni(II) analogue of the Cu(II) complex with the oxygen coordination isomer. The observed linkage isomerism of the oximato group and the suggested formulations of the metal complexes are based on analytical, electronic and vibrational spectra, and magnetic-moment evidence.
