In the crystal structure of the polymeric title complex, [Cd(C11H10O4)(C10H8N2)]n, the CdII cation is chelated by one 2,2-bipyridine ligand and two carboxyl groups from two trimethyl­isophthalate (TMIPA) anions, and is further coordinated by one carboxyl­ate O atom from a third TMIPA anion, forming a distorted penta­gonal–bipyramidal geometry. Each TMIPA anion bridges three CdII cations, forming polymeric complex sheets parallel to (001). Weak C—H⋯O hydrogen bonding occurs between adjacent sheets.

Comment top

The rational design and synthesis of functional metal-organic frameworks (MOFs) is a more and more fascinating field in recent years due to their interesting topologies and potential applications in gas adsorption, nonlinear optics, magnetism, molecular recognition, etc (Evans & Lin, 2002; Chen, et al., 2010; Leong & Vittal, 2011; Sun et al., 2011). As we know, the construction of MOFs mainly depends on the coordination geometry of metal ions and the nature of ligands. Besides, some secondary interactions, such as aromatic π···π interactions, classical hydrogen bonds (such as O-H···O and N-H···O hydrogen bonds), and non-classical hydrogen bonds (such as C-H···O hydrogen bond) often influence the packing of molecules from discrete subunits or low-dimentional entities to high-dimentional supramolecular frameworks. One of the most effective strategies to assemble MOFs is to use carboxylates as linkers because of their diverse conformations and coordination modes observed in the coordination process (Ma et al., 2008; Zhang et al., 2008). In spite of isophthalate-based MOFs (Zhou et al., 2003; Zhang et al., 2003) have been widely reported, to the best of our knowledge, only one MOF based on 2,4,6,-trimethylisophthalic acid (H2TMIPA) has been documented until now (He et al., 2010). Based on our previous work (Dai et al., 2008; Dai et al., 2009; Zhao et al., 2009) and consideration the steric hindrance effects of additional three methyl groups on isophthalate, herein, we choose the H2TMIPA as a bridging ligand to construct a novel CdII coordination polymer (I), which is a 2D (4,4) net incorporating [Cd2(COO)4N2] SBUs.

The asymmetric unit of (I) contains one crystallographically independent CdII center, one TMIPA ligand and one bpy ligand. The CdII ion is in a slightly distorted pentagonal bipyramidal geometry, completed by five O atoms from three different TMIPA ligands and two N atoms from the same bpy ligand (Fig. 1). The equatorial plane of pentagonal bipyramid is defined by O2i, O3ii, O4ii, N2 atoms, while the axial positions are occupied N1, O1 atoms. [symmetry codes: (i) -x+1, -y+1, -z+1; (ii) -x+3/2, y+1/2, z]. Two carboxyl groups on TMIPA ligand adopt two different coordination patterns, µ1-η1: η1 chelating and µ2-η2: η1 bridging, respectively. The Cd-N bond lengths are 2.393 (4) and 2.334 (4) Å, while the Cd-O bond lengths vary from 2.317 (3) to 2.607 (3) Å (Table). The average Cd-N and Cd-O distances in (I) are comparable with those reported for Cd-based MOFs (Liu et al., 2008). Two crystallographically equivalent CdII anions are bridged by two tridentate bridging carboxyl groups to form a binuclear SBU with a Cd···Cd contact of 3.7886 (6) Å. Because of the steric hindrance between the methyl and the carboxyl groups, the two carboxyl groups of H2TMIPA are not coplanar with the central benzene ring, generating two dihedral angles of 55.1 (2) and 85.3 (2)o, respectively. The [Cd2(COO)4N2] SBUs are joined by TMIPA ligands to form an infinite 1D zigzag chain. Furthermore, TMIPA ligands connect the zigzag chain to a 2D layer (Fig. 2) which is consolidated by the intrasheet weak face-to-face π···π interaction between bpy and TMIPA with Cg1···Cg2i separation of 3.725 (3) Å (Cg1 and Cg2 are the centroids of the N1/C1–C5 and C12–C17 rings, respectively; symmetry code: (i) -x+1, -y+1, -z+1). The bpy ligand acts as a terminal group to occupy the remaining coordinate sites, which prevents the structure from higher dimensionalities. The adjacent 2D layers are further extended to a 3D supramolecular framework by virtue of non-classical C-H···O hydrogen bonds (Table 2).

Experimental top

A mixture of Cd(NO3)2.6H2O (30 mg, 0.12 mmol), 2,4,6,-trimethylisophthalic acid (H2TMIPA) (20 mg, 0.12 mmol) and bipyridine (10 mg, 0.06 mmol) was suspended in 15 mL mixed solvents of N,N'-dimethylformamide, ethanol and H2O (v/v = 1:1:1), and heated in a Teflon-lined steel bomb at 373 K for 4 days. After cooling to room temperature, colorless crystals were collected, washed with ethanol several times, and dried in the air (yield: 47%, based on H2TMIPA).

Refinement top

H atoms were generated geometrically and were allowed to ride on their parent atoms in the riding model approximations with C—H = 0.93 (aromatic) and 0.96 Å (methyl), Uiso(H) = 1.2Ueq(C) for aromatic H atoms and 1.5Ueq(C) for methyl H atoms.

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 > 2sigma(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.
