title: Crystal structure of catena-poly[[di-aqua(4,5-di-aza-fluoren-9-one-κ(2) N,N')cadmium]-μ-2-hydroxy-5-sulfonato-benzoato-κ(3) O (1),O (1'):O (5)].
abstract: In the polymeric title compound, [Cd(C7H4O6S)(C11H6N2O)(H2O)2] n , the Cd(2+) atom is seven-coordinated by two water O atoms, by three O atoms from two 2-hy-droxy-5-sulfonato-benzoate (Hssal(2-)) ligands and by two N atoms from a 4,5-di-aza-fluoren-9-one (Dafo) ligand in a distorted penta-gonal-bipyramidal geometry. The Cd(2+) atoms are monodentately coordinated by the sulfonate group of one Hssal(2-) ligand and bidentately coordinated by the carboxyl-ate group of another Hssal(2-) ligand, generating zigzag chains running parallel to [010]. The chains are linked by O-H⋯O hydrogen bonds into a three-dimensional architecture.
