Supporting information
A mixture of Cd(Ac)2(0.5 mmol), 4,4'-sulfonyldi-p- phenylenedioxydiacetic acid (0.5 mmol), NaOH (1 mmol) and H2O (15 ml) was placed in a 23 ml Teflon reactor, which was heated at 413 K for three days and then cooled to room temperature. Colourless blocks were obtained on cooling, which were washed with water and dried in air.
All H atoms were placed in idealized positions (O—H = 0.85 Å and C—H = 0.93–0.97 Å) and refined as riding atoms with Uiso(H) = 1.2Ueq(C) and Uiso(H) = 1.5Ueq(O).

Special details top Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

A large family of coordination polymers has been developed recently owing to their potential applications as functional solid materials and their intriguing architectures or topologies. In the past ten years, there has been a growing interest in metal-organic frameworks involving semi-rigid V-shaped dicarboxylate ligands (Tanaka et al., 2008; Zheng et al., 2009, 2010). 4,4'-sulfonyldi-p-phenylenedioxydiacetic acid is a typical example of a semi-rigid V-shaped dicarboxylate ligand. To the best of our knowledge, there has been no report about its coordination compounds. Recently, we obtained the title cadium polymer (I), its crystal structure is reported here.
In the structure of (I) each cadium(II) atom is coordinated by four oxygen atoms from two 4,4'-sulfonyldi-p-phenylenedioxydiacetate ligands and two water molecules, displays a highly distorted octahedral geometry(Fig. 1). Each ligand L bridges two cadium(II) centers to form polymeric zigzag chain propagated in direction [101](Fig. 2). Moreover, there are Intermolecular O—H···O hydrogen bonds between the coordinated water molecules and the carboxylate O atoms consolidate the further crystal packing(Table 1).
