In the title compound, [Cu(CHO2)2(C12H10N4)], the CuII ion lies on an inversion center and is coordinated by two formate O atoms and two N atoms from two 1,4-bis(imidazol-1-yl)phenyl ligands (L), forming a square-planar coordination environment. The linear molecule L acts as a bidente bridging ligand, connecting the metal atoms into a chain along [101].
