In the title compound, [Cd(C8H3O7S)(C6H13N2)(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.

A 1/1 water–ethanol solution (8 ml) of cadmium nitrate tetrahydrate (0.15 g, 0.5 mmol), the monosodium salt of 5-sulfoisophthalic acid (0.13 g, 0.5 mmol) and diazabicyclo[2.2.2]octane (0.22 g, 2.0 mmol) was placed in a 23 ml Teflon-lined stainless vessel. The vessel was sealed and then heated at 433 K for 60 h, after which it was allowed to cool to room temperature. The crystals that deposited from the solution were collected and washed with water. CHN analysis for C14H18CdN2O8S: found C 34.22, H 3.79, N 6.02%; calculated C 34.54, H 3.73, N 5.75%.

The water and ammonium H atoms were located and refined subject to constraints of O—H = N—H = 0.85±0.01 and H···H = 1.39±0.01 Å. The C-bound H atoms were generated geometrically (C—H = 0.95 Å for the aromatic H atoms and 0.97 Å for the aliphatic H atoms) and were included in the refinement in the riding-model approximation; their displacement parameters were set at 1.2 times those of the equivalent isotropic displacement parameters of the parent C atoms.

The 5-sulfoisophthalato monoanion, [C6H3-1,3-(CO2H)2-5-SO3]−, reacts with copper nitrate in the presence of hexamine to form C6H3-1,3-(CO2)2-5-SO3H](H2O)3Cu·6H2O·0.5(CH2)6N4. In the crystal structure, the [C6H3-1,3-(CO2)2-5-SO3H]2− dianion links adjacent Cu atoms through both monodentate –CO2 groups into a linear chain, and adjacent chains are linked by hydrogen bonds to the water and hexamine molecules into a network motif. The piperazine guest-host analog, [C6H3-1,3-(CO2)2-5-SO3H](H2O)2Cu·6H2O·0.5 N(CH2)4N, follows the similar pattern (Sun et al., 2003). The other known metal complex of 5-sulfoisophthalic acid is also a copper derivative, [C6H3(CO2)2(SO3)]2Cu3, whose Cu atoms are coordinated by pyridine ligands (Kulynych & Shimizu, 2002).
We have employed the anion to react with Cd2+ in the presence of 1,4-diazabicyclo[2.2.2]octane in the hope of synthesizing a similar guest–host hydrate, i.e. [C6H3-1,3-(CO2)2-5-SO3H]Cd–N(CH2CH2)3N.nH2O, (I), using a hydrothermal synthetic procedure. However, in the water-coordinated product, the H atom of the sulfonate group has protonated one of the N atoms of the 1,4-diazabicyclo[2.2.2]octane; the resulting 1-aza-4-azoniabicyclo[2.2.2]octane cation then engages its free N atom to coordinate to the Cd atom, and a zwitterionic compound results (Fig. 1).
The [C6H3-1,3-(CO2)2-5-SO3]3− trianion uses both –CO2 groups to link to adjacent Cd atoms to form a chain, but one of them is monodentate [Cd—O = 2.190 (2) Å] whereas the other is chelating [Cd—O = 2.331 (2) and 2.399 (2) Å]. Two chains are then linked by a sulfonate bridge [Cd—O = 2.349 (2) Å] to furnish a ribbon motif (Fig. 2). The ribbons are further linked by hydrogen-bonding interactions (Table 2) to give rise to a three-dimensional network structure. Protonation of one of the two N atoms of the 1,4-diazabicyclo[2.2.2]octane probably raises the Lewis basicity of the other N atom to permit it to bind to Cd [Cd1—N1 = 2.437 (2) Å]; a Cd← N interaction of a similar length [Cd← N 2.446 (3) Å] is also found in {[NH(CH2CH2)N]2Cd}{Ni(CN)4}2·4C6H5NH2 (Yuge & Iwamoto, 1995).
