title: catena-Poly[[[diaquacadmium(II)]bis[μ-2-(pyridinium-1-yl)butanedioato]-κO:O;κO:O] tetrahydrate], a polymeric chain structure.
abstract: In the title complex, {[Cd(C(9)H(8)NO(4))(2)(H(2)O)(2)]·4H(2)O}(n), the Cd(II) atom (site symmetry 2) is coordinated by six O atoms from four crystallographically related 1-(1,2-dicarboxyl-ate)pyridin-1-ium ligands (L) and from two water molecules in a distorted octahedral geometry. Paired L ligands connect Cd(II) atoms into a chain motif parallel to [001], which is further inter-linked by O-H⋯O hydrogen bonds into a three-dimensional supra-molecular net.
