Hexakis(1H-imidazole-?N)cobalt(III) tris-(hexa-fluoridophosphate) hexa-hydrate.

ABSTRACT: In the crystal structure of the title compound, [Co(C(3)H(4)N(2))(6)](PF(6))(3)·6H(2)O, the Co(III) atom lies on a special position with site-symmetry and the P atom is located on a special position with site symmetry . The Co(III) atom has an almost ideal octa-hedral coordination formed by the N atoms of six imidazole ligands. The water mol-ecules form hydrogen-bonded helical chains propagating in [001] by O-H?O inter-actions with a distance of 2.913?(2)?Å. They simultaneously inter-act as hydrogen-bond acceptors and donors with the cations and anions, respectively, resulting in the formation of a three-dimensional assembly. Weak C-H?F inter-actions further stabilize the crystal structure.
