Os. Jung et al., Trinucleating bipyridyl ligands; Synthesis and structure of cobalt-benzoquinone complex of cyclotriphosphazenes bearing dioxybipyridine groups, INORG CHEM, 38(23), 1999, pp. 5457
Exocyclic tris(bidentate) ligands attached to a cyclo-triphosphazene skelet
on 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.
