1,3-Di-4-pyridylpropane-4,4'-oxydibenzoic acid (1/1)

G. Li, C. Salim and H. Hinode

Abstract top

The hydrothermal reaction of Cd(NO3)2·4H2O, 1,3-di-4-pyridylpropane (BPP) and 4,4'-oxydibenzoic acid (OBA) led to the formation of the title compound, C13H14N2·C14H10O5. The asymmetric unit consists of one molecule of OBA and one of BPP. In the OBA molecule, one COOH group is nearly planar with its attached benzene ring [dihedral angle = 0.9 (1)°], while the other COOH group is slightly twisted with a dihedral angle of 10.8 (3)°. The carboxyl groups form strong intermolecular O-H...N hydrogen bonds with N atoms of the pyridine rings in BPP, linking the molecules into zigzag chains.

Comment top

Over the past decades, the rational design and synthesis of metal-organic frameworks have received extensive attention in the fields of supramolecular chemistry and crystal engineering (Hagrman et al., 1999; Yaghi et al., 1998). These materials exhibit interesting functions such as catalysis, biology, electrical conductivity, magnetism and photochemistry. In the past five years, there has been a growing interest in metal-organic frameworks based on 1,3-di-4-pyridylpropane and 4,4'-oxydibenzoic acid ligands (Wang et al., 2005; Luan et al., 2005; Belcher et al., 2002; Han et al., 2007; Nguyen et al., 2006). Recently, we have focused on preparing metal-organic frameworks containing such organic ligands and metal ions. During the process, a new cocrystal of 1,3-di-4-pyridylpropane and 4,4'-oxydibenzoic acid was obtained which assembled by H-bondin and we report its synthesis and crystal structure here. The structures of some similar molecular materials have been reported (Dai et al., 2005; Lee et al., 2003; Ma et al., 2006; Wang et al., 2008; Hou et al., 2008; Najafpour et al., 2008). An independent study of (I) has also been published (Dong et al., 2008).

As shown in Fig. 1, the asymmetric unit contains one 1,3-di-4-pyridylpropane molecule and one 4,4'-oxydibenzoic acid molecule. The bond lengths and angles are within normal ranges. In 4,4'-oxydibenzoic acid molecule, one COOH group (C7/O2/O3) is nearly planar with one benzene ring (C1/C2/C3/C4/C5/C6, dihedral angle of 0.9 °), while another COOH group (C14/O4/O5) has a dihedral angle of 10.8 ° with another benzene ring (C8/C9/C10/C11/C12/C13). The dihedral angle between two benzene ring of a 4,4'-oxydibenzoic acid molecule is 57.0 °. In 1,3-di-4-pyridylpropane molecule, the dihedral angle between two pyridyl rings is 26.9 °. The carboxylic acid groups form strong intermolecular O—H···N hydrogen bonds (Table 1) with N atoms of the pyriding rings, linking the molecules into one-dimensional zigzag chains (Fig.2). Intermolecular C—H···O hydrogen bonds may be effective in the stabilization of the crystal structure.

Experimental top

In a typical synthesis for the title compound, a mixture of Cd(NO3)2.4H2O 120 mg, 4,4'-oxydibenzoic acid 52 mg, 1,3-bis(4-pyridyl)propane 20 mg, HCl (38%) 0.1 ml, NH3.H2O 0.08 ml, N,N-dimethylformamide (DMF) 3.0 ml and H2O 6.0 ml were sealed in a 15 ml Teflon-lined stainless steel autoclave and heated under autogenous pressure for five days at 393 K. After slow cooling to room temperature, the block-shaped colourless crystalline product was filtered, washed with distilled water, and dried at ambient temperature. The crystal used for data collection was obtained directly from the sample that was washed and dried without further re-crystallization.

Refinement top

The C-bound H atoms were positioned geometrically with C—H = 0.93–0.97 Å, and allowed to ride on their parent atoms with Uiso(H) = 1.2 Ueq(C). The H atoms on oxygen atoms of carboxylic acid groups were found in a difference map and refined with a riding model with O—H = 0.82 Å and Uiso(H) = 1.2 Ueq(C).

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.
