Crystal structure of catena-poly[bis­­(acetato-κO)copper(II)]-bis­­[μ-4-(1H-imidazol-1-yl)phenol]-κ2N3:O;κ2O:N3]

In the title compound, [Cu(CH3COO)2(C9H8N2O)2]n, the CuII 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⋯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⋯O hydrogen bonds and by π–π stacking inter­actions involving centrosymmetrically related pairs of imidazole and phenol rings.
