In the title compound, [Cu(CH3COO)(2)(C9H8N2O)(2)] n, the Cu II ion resides on a centre of inversion, displaying a tetragonally distorted octahedral coordination environment defined by two pairs of N and O atoms of symmetry-related 4-(1H-imidazol-1-yl)phenol ligands and the O atoms of two symmetry-related acetate ligands. The bridging mode of the 4-(1H-imidazol-1-yl) phenol ligands is associated with a very long Cu center dot center dot center dot O interactions involving the phenol O atom of the heterocyclic ligand, which creates chains extending parallel to [100]. In the crystal, the chains are arranged in a distorted hexagonal rod packing and are linked via C-H center dot center dot center dot O hydrogen bonds and by pi-pi stacking interactions involving centrosymmetrically related pairs of imidazole and phenol rings.
