Abstract: In the crystal structure of the title compound, [Co(C₃H₄N₂)₆](PF₆)₃·6H₂O, 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 octahedral coordination formed by the N atoms of six imidazole ligands. The water molecules form hydrogen-bonded helical chains propagating in [001] by O-HO 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-HF interactions further stabilize the crystal structure.
