Abstract

A new soluble vic-dioxime, 1,4-bis(2-methoxyethyl-2,3-bis(hydroxyimino)-5,6-diphenylpiperazine (LH2) has been synthesized as a mixture of isomers from dicyan di-N-oxide and 1,2-diphenyl-1,2-bis(2'-methoxyethylamino)ethane, 1, which has been prepared through the reduction of the condensation product of benzaldehyde and 2-methoxyethylamine with the aluminium amalgam. LH2 gives N,N-coordinated planar metal complexes with Co-II, Ni-II Cu-II and Pd-II. Oxidation of (LH)(2)Co in the presence of a base such as py or triphenylphoshine leads to octahedral complexes (LH)(2)Co(B)Cl. The uranyl complex of LH2 has a 1:1 metal-ligand ratio and a binuclear structure with mu-hydroxo bridges.
