In the title complex, [Zn2(C8H4O4)(C20H11N4O2)2]·4H2O, the ZnII atom is six-coordinated by two carboxylate O atoms from one bidentate benzene-1,4-dicarboxylate (1,4-BDC) ligand, two carboxylate O atoms from two different monodentate 4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)benzoate (HNCP) ligands and two HNCP N atoms. The ZnII atoms are bridged by the centrosymmetric 1,4-BDC ligands, forming an extended single-chain structure. Neighbouring single chains are connected by the HNCP ligands from two opposite directions, resulting in a sheet. In addition, there are N—H...O hydrogen-bonding interactions between adjacent layers. As a result, the polymeric sheets are further extended into a three-dimensional supramolecular structure.
