In the title compound, {[Cu(C24H15N2O4)2(H2O)2]﹞4C3H7NO}n, the CuII ion, lying on an inversion center, is six-coordinated by two N atoms from two 4-[6-(4-carboxyphenyl)-4,4∩-bipyridin-2-yl]benzoate (L) ligands, two deprotonated carboxylate O atoms from two other symmetry-related L ligands and two water molecules in a slightly distorted octahedral geometry. The CuII atoms are linked by the bridging ligands into a layer parallel to (101). The presence of intralayer O〞H...O hydrogen bonds and 羽每羽 interactions between the pyridine and benzene rings [centroid每centroid distances = 3.808 (2) and 3.927 (2) ] stabilizes the layer. Further O〞H...O hydrogen bonds link the layers and the dimethylformamide solvent molecules.
