Owing to the variety of structures and unique properties, transition metal complexes of oxamide oxime (diaminoglyoxime, oaoH 2 ) are of great interest. So far, most of the published work concerns 4-coordinated transition metal oxamide oximate complexs (Endres, 1980;Endres & Schlicksupp, 1980;Endres et al, 1983). The 6-coordinated transition metal oxamide oximate complexes have not been reported hitherto (Bélombé et al, 2006;Belombe et al, 2007;Egharevba et al, 1982).…”

“…The amino groups tend to be involved in H bridges as well. Such intermolecular H bridges lead to a rich structural chemistry in the solid state (Endres, 1980(Endres, , 1982a and allow the synthesis of new molecular electron conductors (Endres, Bongart, N6the, Hennig, Schweitzer, Schiifer, Helberg & Flandrois, 1985). The title compound is another example of the unusual stacking patterns found in oxamide oximato complexes.…”
