The structure of copper(II) hinokitiol has been determined. Two modifications are possible, one containing only isolated, four-coordinate, square-planar complexes, while a second modification contains both monomers, along with eclipsed and staggered dimers generated through intermolecular O→Cu interactions. Five-coordinate copper is also present in the adduct Cu(hino) 2·pyridine, whose structure has also been determined for comparison. Copper hinokitiol crystallises in both monomeric and dimeric forms, the latter involving both staggered and eclipsed arrangements of monomers. The versatility of the coordination chemistry displayed by copper hinokitiol is unique among metal derivatives of α-hydroxyketone ligands. The ability of copper hinokitiol to form acceptor complexes with N-donor ligands is also demonstrated.
