The title polymeric compound, [Cu2(C8H7O2)4]n, was synthesized by the reaction of copper acetate with aqueous phenylacetic acid. The unique CuII atom is coordinated by five O atoms from the carboxylate groups of phenylacetate ligands, and the strongly distorted octahedral coordination environment is completed by a Cu—Cu bond of 2.581 (2) Å, at whose mid-point is located an inversion centre. The crystal structure consists of infinite polymeric linear chains of Cu2+ ions, running along [100], linked by bridging phenylacetate groups.
