Hexakis(1H-imidazole-κN3)cobalt(III) tris(hexafluoridophosphate) hexahydrate

Abstract

In the crystal structure of the title compound, [Co(C3H4N2)6](PF6)3·6H2O, the CoIII atom lies on a special position with site-symmetry overline{3} and the P atom is located on a special position with site symmetry overline{1}. The CoIII atom has an almost ideal octahedral coordination formed by the N atoms of six imidazole ligands. The water molecules form hydrogen-bonded helical chains propagating in [001] by O—H...O interactions with a distance of 2.913 (2) Å. They simultaneously interact 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 interactions further stabilize the crystal structure.
