Abstract: In the title compound, {[Cd(C₈H₄O₄)(C₁₁H₆N₂O)(H₂O)₃]·2H₂O}_n, the Cd^II 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 - interactions [centroid-centroid distances = 3.325 (3) and 3.358 (4) Å] and O-HO hydrogen-bonding, resulting in a two-dimensional network extending parallel to (001).
