Abstract

The title compound, [Co(C₇₂H₄₈N₆)](PF₆)₃·H₂O, crystallizes with one tripositive complex mol-ecule, three hexa-fluoro-phosphate anions and one solvent mol-ecule of water in the asymmetric unit. The N₆ coordination set around the central Co^III atom defines a distorted octa-hedral environment. Four fluorine atoms of one hexa-fluoro-phosphate anion are disordered over two sets of positions with site-occupancy factors of 0.697 (5) and 0.303 (5). In the crystal, inter-molecular π-π stacking inter-actions, C-H⋯π, C-H⋯F and O-H⋯F and inter-actions are present.
