In the title complex, [Cd2(C17H14O4S)2(C10H8N2)2], which was hydrothermally synthesized, the CdII cation is hexacoordinated in a distorted octahedral geometry by two N atoms from a 2,2′-bipyridine ligand and by four O atoms from two different 2-[3-carboxylatomethyl-4-(phenylsulfanyl)phenyl]propanoate ligands, forming a cyclic dimetallic complex.

H2L (0.5 mmol) and 2,2'-bipyridine (0.5 mmol) were dissolved in a mixture of 5 ml of ethanol and 15 ml of H2O to which an aqueous solution of sodium hydroxide was added dropwise with stirring to adjust the pH to 6. After addition of 10 ml of an aqueous solution of cadmium chloride (0.5 mmol) the mixture was heated at 403 K for 3 days. After cooling to room temperature, the reaction solution was filtered to remove a small quantity of white precipitate. Slow evaporation of the filtrate at room temperature over three days produced X-ray quality colorless block-shaped single crystals.
H atoms were positioned geometrically and refined as riding atoms with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic H atoms, C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C)for methylene H atoms, and C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for methyl H atoms. Atoms C17 and C18 are disordered over two distinct sites in a 77:23 ratio. The two components of this disorder were refined with restraints to make their geometries similar.
The design and synthesis of coordination polymers is of great interest due to their intriguing topologic architecture and significant application in many fields (Pan et al., 2004; Batten et al., 1998). Among the variety of organic molecules acting as linkers in the design of supramolecular networks, heterocyclic N rings and polycarboxylates are the most widely used ligands due to their rigidity in structure and flexibility in coordination modes (Moulton et al., 2001; Wang et al., 2004; Lu et al., 2003). In this work we report a cyclic CdII coordination complex, (I), constructed from 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid and 2,2'-bipyridine (Fig. 1). The O—Cd bond distances range from 2.277 (6) to 2.416 (6) Å and the Cd—N bond distances are 2.311 (3) and 2.320 (3) Å. The dihedral angle between two benzene rings in the same L ligand is 78.73 (6)° and the C—S—C angle is 102.11 (6)°. It is to be noted that both carboxylates of L are bidentate but asymmetrically coordinated with the Cd1—O1 and Cd1—O2 bond distance of 2.276 (3) and 2.415 (3) Å, respectively while the Cd1—O3 and Cd1—O4 distances are 2.345 (3) and 2.309 (3) Å. These differences can likely be attibuted to packing considerations since of the four carboxylate oxygen atoms, only O1 is not involved with C—H···O hydrogen bonding interactions. The self-assembly of the metal with 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid and 2,2'-bipyridine links the Cd ions into a cyclic dimer (Fig. 1). Weak π-π stacking interactions between pyridine rings from different bipy ligands (interplanar spacing = 3.708 (4) Å, dihedral angle between planes = 1.07 (4)°) as well as a number of short (C—H···X (X = O, N)) contacts generate a 3-D structure (Fig. 2).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

The design and synthesis of coordination polymers is of great interest due to their intriguing topologic architecture and significant application in many fields (Pan et al., 2004; Batten et al., 1998). Among the variety of organic molecules acting as linkers in the design of supramolecular networks, heterocyclic N rings and polycarboxylates are the most widely used ligands due to their rigidity in structure and flexibility in coordination modes (Moulton et al., 2001; Wang et al., 2004; Lu et al., 2003). In this work we report a cyclic CdII coordination complex, (I), constructed from 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid and 2,2'-bipyridine (Fig. 1). The O—Cd bond distances range from 2.277 (6) to 2.416 (6) Å and the Cd—N bond distances are 2.311 (3) and 2.320 (3) Å. The dihedral angle between two benzene rings in the same L ligand is 78.73 (6)° and the C—S—C angle is 102.11 (6)°. It is to be noted that both carboxylates of L are bidentate but asymmetrically coordinated with the Cd1—O1 and Cd1—O2 bond distance of 2.276 (3) and 2.415 (3) Å, respectively while the Cd1—O3 and Cd1—O4 distances are 2.345 (3) and 2.309 (3) Å. These differences can likely be attibuted to packing considerations since of the four carboxylate oxygen atoms, only O1 is not involved with C—H···O hydrogen bonding interactions. The self-assembly of the metal with 5-(1-carboxyethyl)-2-(phenylthio)phenylacetic acid and 2,2'-bipyridine links the Cd ions into a cyclic dimer (Fig. 1). Weak π-π stacking interactions between pyridine rings from different bipy ligands (interplanar spacing = 3.708 (4) Å, dihedral angle between planes = 1.07 (4)°) as well as a number of short (C—H···X (X = O, N)) contacts generate a 3-D structure (Fig. 2).
