| Abstract: | In the isomorphous title compounds, Cd2(C8H4O4)2(C19H10ClFN4)2(H2O)2] and Zn2(C8H4O4)2(C19H10ClFN4)2(H2O)2], the CdII centre is seven‐coordinated by two N atoms from one 2‐(2‐chloro‐6‐fluorophenyl)‐1H‐imidazo4,5‐f]1,10]phenanthroline (L) ligand, one water O atom and four carboxylate O atoms from two different benzene‐1,2‐dicarboxylate (1,2‐bdc) ligands in a distorted pentagonal–bipyramidal coordination, while the ZnII centre is six‐coordinated by two N atoms from one L ligand, one water O atom and three carboxylate O atoms from two different 1,2‐bdc ligands in a distorted octahedral coordination. Each pair of adjacent metal centres is bridged by two 1,2‐bdc ligands to form a dimeric structure. In the dimer, each L ligand coordinates one metal centre. The dimer is centrosymmetric, with a crystallographic inversion centre midway between the two metal centres. The aromatic interactions lead the dimers to form a two‐dimensional supramolecular architecture. Finally, O—H...O and N—H...O hydrogen bonds reinforce the two‐dimensional structures of the two compounds. |
