The title complex, [Cu(C9H6NO)2(C5H4N)]·H2O, adopts a slightly distorted square-pyramidal geometry in which the axial pyridine ligand exhibits a long Cu—N bond of 2.305 (3) Å. The pyridine ligand forms dihedral angles of 79.5 (5) and 88.0 (1)° with the planes of the two quinolin-2-olate ligands, while the dihedral angle between the quinoline groups of 9.0 (3)° indicates near planarity. The water molecule connects adjacent copper complexes through O—H...O hydrogen bonds to phenolate O atoms, forming a network interconnecting all the complexes in the crystal lattice.

A discrete ammonium catecholate hydrate of the compositionNH4[C6H4(OH)2][C6H4(OH)O] · 0.5 H2O has been isolated and characterized by a single-crystal X-ray structure analysis. The crystals are monoclinic, space group C 2/c (No. 15), Z = 8, a = 24.613(3), b = 8.706(1), c = 11.890(2) Å, β = 110.56(1)°. The crystal lattice features a network of hydrogen bonds, which clearly contribute significantly to the overall stability of the lattice. The water molecule is engaged as a donor and an acceptor in as many as four hydrogen bonds. Surprisingly, the crystalline compound is air-stable, while anhydrous ammonium catecholate, as obtained by dissolving catechol in dry liquid ammonia, is quickly oxidized in air.
