Abstract

In the title compound, {[Cd(C8H4O4)(C11H6N2O)(H2O)3]·2H2O}n, the CdII atom is seven-coordinated by two N atoms from the phenanthroline-derived 4,5-diazafluorene-9-one ligand, two O atoms from one bidentate benzene-1,3-dicarboxylate ligand and three O atoms from the three water molecules in a distorted pentagonal-bipyramidal arrangement. Moreover, there are two dissociative water molecules in each unit. Neighbouring units interact through π–π interactions [centroid–centroid distances = 3.325 (3) and 3.358 (4) Å] and O—H...O hydrogen-bonding, resulting in a two-dimensional network extending parallel to (001).
