Abstract

In the title compound, [Ni(C15H11N3)2](ClO4)2·0.5H2O, the Ni2+ cation is coordinated by two terpyridine ligands to form a discrete complex and the coordination polyhedron can be described as a slightly distorted octa­hedron. It crystallizes as a hemihydrate with two perchlorate anions to compensate the charges. In the crystal, one of the two crystallographically independent perchlorate anions is involved in O-H...O hydrogen bonding to the water mol­ecules, where two inversion-related water mol­ecules link two inversion-related perchlorate anions into a ring with an R42(12) loop. The O-atom position of the water mol­ecule is only half occupied, i.e. only half of the anions are involved in hydrogen bonding. A similar arrangement of two anions is also observed for the second crystallographically independent perchlorate anion but no water mol­ecules are located between the anions. The cationic complex and the perchlorate anions are additionally linked by a number of weak C-H...O hydrogen bonds, forming a three-dimensional supra­molecular structure. The crystal structure of the monohydrate of the same complex has been reported [Baker et al. (1995). Aust. J. Chem. 48, 1373-1378].
