Poly[[aqua(1-aza-4-azoniabicyclo[2.2.2]octane)-cadmate(II)] -μ-5-sulfatoisophthalato]

In the title compound, [Cd(C₈H₃O₇S)(C ₆H₁₃N₂)(H₂O)]_n, the Cd atom is coordinated by one O atom of a carboxylate group of a 5-sulfatoisophthalato ligand, two O atoms of the carboxylate group group of an adjacent symmetry-related 5-sulfoisophthalato entity, one O atom of the sulfonyl group of yet another adjacent 5-sulfatooisophthalato entity, a water molecule and the N atom of the 1-aza-4-azoniabicyclo[2.2.2]-octane cation in a six-coordinate octahedral geometry. Thus, the mode of coordination of the 5-sulfatoisophthalato ligand leads to the formation of a linear ribbon motif; adjacent ribbons are linked by hydrogen-bonding interactions, giving rise to a three-dimensional network structure.
