1,4-Bis(2-methylimidazole-1-methyl)benzene was prepared by the method of Hoskins et al. (1997). A mixture of Zn(NO3)2.6H2O (298 mg,1 mmol), 1,4-bis(2-methylimidazole-1-methyl)benzene (1.0 mmol, 266.4 mg), 1,2,4,5-benzenetetracarboxylic acid (1.0 mmol, 254.2 mg) and H2O (12 mL) was placed in a Teflon-lined stainless vessel and heated to 393 K for 4 days under autogenous pressure, and then cooled to room temperature in 24 h. block-shaped colourless crystals of (I) suitable for single-crystal X-ray
were obtained.H atoms bonded to C atoms and hydroxy H atoms were placed in calculated positions with C–H = 0.93 or 0.97 Å, O-H = 0.82Å and refined using a riding-model approximation with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(O, Cmethyl). Water H atoms and N-bound H atoms were located in a difference Fourier map and included in their 'as found' positions with Uiso(H) = 1.5Ueq(O, N).

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. |

1,4-bis(2-methylimidazole-1-methyl)benzene is a flexible bridging ligand, which can participate in the construction of coordination polymers and can provide information on the influences of 2-substituted derivatives of imidazole on the structures and properties of resulting complexes (Liu et al., 2011a,2011b). In our attempt to synthesize a zinc complex with this ligand, we unexpectedly obtained the title compound (I) and report herein its synthesis and crystal structure determination.
The asymmetric unit of (I) is shown in (Fig. 1). Bond distances and angles are as found in other structures (Liu Wu, Wan et al., 2011); Liu, Wu, Zhang & Cui, 2011). In the dication, the dihedral angles formed by the mean-planes of the imidazole rings and the benzene ring (C11-C16) are 69.05 (18)° (N1/N2/C18/C19/C20) and 89.1 (2)° (N3/N4/C23/C24/C25). In the crystal, the components are linked into a three-dimensional network by intermolecular N—H···O and O—H···O hydrogen bonds.
