Crystal structure of {2,2′-[N,N′-bis­(pyridin-2-yl­meth­yl)cyclo­hexane-trans-1,2-diyldi(nitrilo)]di­acetato}­cobalt(III) hexa­fluorido­phosphate

The title compound [Co(C22H26N4O4)]PF6, commonly known as [Co(bpcd)]PF6, where bpcd(2-) is derived from the historical ligand name N,N'-bis-(2-pyridyl-meth-yl)-trans-1,2-di-amino-cyclo-hexane-N,N'-di-acetate, crystallized by slow evaporation of a saturated aceto-nitrile solution in air. The cation of the hexa-fluorido-phosphate salt has the Co(III) atom in… (More)
