-1,4-bis(imidazol-1-ylmethyl)benzene]--4,4'-oxydibenzoato]In the title compound, [Zn(C14H8O5)(C14H14N4)]n, the coordination polyhedron around each ZnII atom is a distorted tetrahedron. The ligands bridge the Zn atoms to form a two-dimensional (4,4)-network.
A mixture of H2oba (0.5 mmol), L (0.5 mmol), NaOH (1 mmol) and ZnCl2.6H2O (0.5 mmol) was suspended in 12 ml of deionized water and sealed in a 20 ml Teflon-lined autoclave. Upon heating at 170°C for one week, the autoclave was slowly cooled to room temperature. The crystals were collected, washed with deionized water and dried.
H atoms were generated geometrically and refined as riding atoms with C—H = 0.93 Å and Uiso(H) = 1.2 times Ueq(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. |

Metal–organic frameworks is currently of great interest because of their interesting structures and potential applications. As a good candidate for rigid rod-like spacers in the construction of metal–organic polymers, 4,4'-bipyridine has been relatively well known and has shown hundreds of interesting supramolecular architectures (Batten & Robson, 1998). However, the flexible ligands such as 1,4-bis(imidazol-1-ylmethyl)benzene (L) has not been well explored to date (Ma et al., 2003). In this work, I selected 4,4'-oxybis(benzoic acid) (H2oba) and L as linkers, generating a new coordination polymer, [Zn(oba)(L)], (I), which is reported here.
In compound (I) each ZnII atom is four-coordinated by two N atoms from one L ligand, and two O atoms from two oba carboxylate anions in a distorted tetrahedral coordination sphere (Fig. 1). The two neighbouring ZnII atoms are bridged by the oba and L ligands to form a two-dimensional (4,4) network (Fig. 2).
