In the title compound, {[Zn(C24H15N2O4)2(H2O)2]·4C3H7NO}n, the ZnII ion is located on an inversion center and is six-coordinated by two N atoms from two ligands, two carboxylate O atoms from two other symmetry-related ligands and two O atoms from two water molecules, furnishing a slightly distorted octahedral geometry. The ZnII atoms are connected by the bridging ligands into a layer parallel to (101). O-H...O hydrogen bonds link the layers and the dimethylformamide solvent molecules. [pi]-[pi] interactions between the pyridine and benzene rings [centroid-centroid distances = 3.7428 (17) and 3.7619 (17) Å] and intralayer O-H...O hydrogen bonds are also present.
