(Received 22 November 2008; accepted 5 December 2008; online 10 December 2008)

In title compound, [Cd(C9H6N2O2S)(C12H8N2)]n, the CdII atom is in a distorted tetra­gonal-pyramidal environment, coordinated by one chelating 1,10-phenanthroline ligand, one chelating 2-(1,3-benzimidazol-2-ylsulfan­yl)acetate (bia) ligand bound through one N atom and one O atom of the carboxyl group, and one N atom from a second bia ligand. Each bia ligand acts as bridge between CdII ions, forming one-dimensional coordination polymers along [010], with a shortest Cd⋯Cd distance of 4.27 (2) Å.

Comment top

Recently, there has been significant interest in the rational design and synthesis of metal-organic coordination architectures by using flexible bridging units because the flexibility and conformational freedom of such ligands offers the possibility for construction of unprecedented frameworks (Zhang et al. 2008). Benzimidazole and thioether carboxylates have been widely used to construct many novel and interesting metal-organic frameworks. However, such metal-organic frameworks formed by bifunctional ligands including benzimidazole and thioether carboxylate have been rarely reported (Matthews et al. 1998). Herein, we report a new bifunctional flexible ligand 2-(1H-benzo[d]imidazol-2-ylthio)acetic acid (H2bia), and present the synthesis and structural characterization of a one-dimensional coordination polymer {Cd(bia)(phen)}n (phen = 1,10-phenanthroline).

The asymmetric unit of the title compound, contains a CdII cation, a bia and a chelating phen. Each CdII displays a distorted tetragonal pyramidal geometry, being surrounded by one phen ligand, one chelating bia and a N atom of another bia ligand. Each bia ligand acts as a bridge between two CdII ions, forming one-dimensional coordination polymers along the b axis (Fig. 1). The shortest Cd···Cd distance in the chain is 4.27 (2) Å.

Experimental top

A mixture of H2bia (0.0208 g, 0.1 mmol), phen (0.0180 g, 0.1 mmol), Cd(NO3)2.6H2O (0.0345 g, 0.1 mmol) and H2O (8 ml) was heated in a 15 ml Teflon-lined autoclave at 433 K for 3 days, followed by slow cooling (5 K h-1) to room temperature. The resulting mixture was washed with water, and colourless block crystals were collected and dried in air. Yield 86% (42.9 mg), based on MnII.

Refinement top

H atoms were positioned geometrically and refined using a riding model with C—H = 0.93 or 0.97 Å and with Uiso(H) = 1.2Ueq(C).

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.
