Trinucleating bipyridyl ligands; Synthesis and structure of cobalt-benzoquinone complex of cyclotriphosphazenes bearing dioxybipyridine groups

Abstract

Exocyclic tris(bidentate) ligands attached to a cyclo-triphosphazene skeleton have been prepared and characterized. The cobalt complexes of the ligand have an unusual structure and demonstrate Co-III/Co-II equilibrium over a wide temperature range.
