چکیده
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 a distorted octa-hedral coordination geometry provided by an N4O2 donor atom set. The acetate groups, which are oriented trans with respect to each other, exhibit monodentate coordination whereas the pyridyl N atoms are coordinating in a cis configuration. The geometry of the cation is compared to the geometries of other di-amino di-acetate complexes with Co(III).
