(Received 5 January 2011; accepted 10 January 2011; online 29 January 2011)

In the title coordinaltion polymer, [Cd(C₈H₄O₄)(C₈H₇N₃)₂]_n, the Cd^II atom, lying on a twofold rotation axis, is six-coordinated by two carboxylate O atoms from two benzene-1,3-dicarboxylate (m-BDC) ligands and four N atoms from two chelating 2-(2-pyridyl)imidazole molecules, forming a slightly distorted octahedral geometry. The m-BDC ligand is located over a twofold rotation axis. The Cd^II atoms are bridged by the m-BDC ligands, leading to a wave-shaped chain structure along [010]. N—H⋯O hydrogen bonds connect the chains.

Comment top

Currently, the design and synthesis of metal-organic frameworks (MOFs) are of great interest owing to their intriguing variety of architectures and their tremendous potential applications in many fields (Chen et al., 2009; Rosi et al., 2003; Su et al., 2004; Xiao et al., 2006). As a multidentate ligand, benzene-1,3-dicarboxylic acid (m-H₂BDC) has two carboxyl groups and, therefore, has been widely reported as a good candidate not only in the construction of various coordination polymers but also in the construction of MOFs with multi-dimension (Banerjee et al., 2008; Che et al., 2009; Clegg & Russo, 2009; Li et al., 2008; Su et al., 2009; Zhao, 2008).

In the title coordinaltion polymer (Fig. 1), the central Cd^II ion is six-coordinated by two carboxylate O atoms from two m-BDC ligands and four N atoms from two 2-(2-pyridyl)imidazole (2-PyIM) molecules (Table 1), forming a slightly distorted octahedral geometry. The Cd^II ions are bridged by the m-BDC ligands, leading to a wave-shaped chain structure, as shown in Fig. 2. N—H···O hydrogen bonds connect the chains (Table 2).

Experimental top

All chemicals were purchased from commercial sources and used without further purification. CdSO₄.8H₂O (0.033 mmol), m-H₂BDC (0.1 mmol) and 2-PyIM (0.2 mmol) were dissolved in 15 ml of water. The mixture was stirred for 2 h at room temperature and then heated in a 30 ml Teflon-lined stainless steel autoclave for 3 d at 323 K. After the autoclave was cooled to room temperature, colorless block crystals were harvested.
