A new soluble vic-dioxime 1,4-(isobutyl)-2,3-bis-(hydroxyimino)-5,6-phenylpiperazine was prepared as a mixture of isomers from anti-dichloroglyoxime and N,N'-bis-(isobutyl)stilbendiamine which reacts to N,N-coordinated planar metal complexes with Ni(II), Cu(II), Co(ll), and Pd(II). Oxidation of the Co(II) complex in the presence of pyridine leads to an octahedral complex containing pyridine and chloride as axial ligands in addition to the vic-dioxime ligands. The uranyl complex has a 1: 1 metal:ligand ratio and a dinuclear structure with p-hydroxo bridges.
