In the title compound, [Zn(C7H4ClO2)2(C10H8N2)], the ZnII atom is coordinated by two O atoms from two 4-chlorobenzoate ligands and two N atoms from a chelating 2,2′-bipyridine (bpy) molecule in a distorted N2O2 tetrahedral geometry. The ZnII atom is located on a twofold rotation axis, which also passes through the mid-point of the central C—C bond of the bpy ligand. In the crystal, weak C—H...O hydrogen bonds and π–π stacking interactions between the pyridine rings of the bpy ligands [centroid–centroid distance = 3.642 (3) Å] link the complex molecules into a two-dimensional supramolecular structure parallel to (100). An intramolecular C—H...O hydrogen bond is also observed.
