title: Triaqua-(benzene-1,3-dicarboxyl-ato)(4,5-diaza-fluoren-9-one)cadmium(II) penta-hydrate.
abstract: In the title compound, [Cd(C(8)H(4)O(4))(C(11)H(6)N(2)O)(H(2)O)(3)]·5H(2)O, the Cd(II) atom is seven-coordinated by two N atoms from one bidentate phenanthroline-derived ligand and by five O atoms, two from one bidentate benzene-1,3-dicarboxyl-ate (1,3-BDC) ligand and three from water mol-ecules, in a distorted penta-gonal-bipyramidal geometry. Neighbouring units inter-act through π-π inter-actions [centroid-centroid distances = 3.380 (3) and 3.283 (4) Å]. Finally, three types of O-H⋯O hydrogen bonds exist between coordinated dissociative water mol-ecules and hybridization water mol-ecules and carboxyl-ate O atoms, resulting in a two-dimensional network parallel to (010).
