Crystal structure of catena-poly[[bis-(acetato-κO)copper(II)]-bis-[μ-4-(1H-imidazol-1-yl)phenol]-κ(2)N(3):O;κ(2)O:N(3)].

In the title compound, [Cu(CH3COO)2(C9H8N2O)2] n , the Cu(II) ion resides on a centre of inversion, displaying a tetra-gonally distorted octa-hedral 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⋯O inter-actions 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 hexa-gonal rod packing and are linked via C-H⋯O hydrogen bonds and by π-π stacking inter-actions involving centrosymmetrically related pairs of imidazole and phenol rings.
