A mixture of 1,4-bis(benzimidazol-2-yl)butane (Chen et al., 2002) (2.90 g, 10 mmol) and NaOH (0.80 g, 20 mmol) in DMSO (30 ml) was stirred at 60°C for 1 h, then 4-(chloromethyl)pyridine (5.10 g, 40 mmol) was added. The mixture was cooled to room temperature after stirring at 60°C for 24 h, and then poured into 200 ml of water. A colorless solid of L formed immediately, which was isolated by filtration in 65% yield after drying in air. Crystals suitable for X-ray diffraction were grown from 70% ethanol.
All H atoms on C atoms were poisitioned geometrically and refined as riding atoms, with C—H = 0.93–0.97 Å, and Uiso = 1.2 or 1.5 Ueq (C). The H atoms of the water molecule were located in a difference Fourier map and then refined isotropically.

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. |

The research on coordination polymers exhibiting novel structures and properties is an attractive field (Leininger et al., 2000). The key factor for construction of coordination polymers is the selection of the organic ligand. Among various organic ligands, flexible N-donor ligands are beneficial when trying to form helical and interpenetrating structures (Chesnut et al., 1999; Chu et al., 2007; Liu & Tilley 1997; Lo et al., 2000; Tong et al., 1999). In this paper, we describe the isolation and structural characterization of a new N-donor neutral ligand, 1,4-bis(1-(pyridin-4-ylmethyl)-1H-benzo[d]imidazol-2-yl)butane (hereafter L).
The asymmetric part of the unit cell contains two crystallographically independent L molecules located each on an inversion center and two water molecules (Fig. 1). The butyl groups in different L molecules display TTT (T = trans) conformations. The dihedral angles between the phenyl and pyridine rings are 82.2 and 106.2°, respectively, in the two different L molceules. The water molecules are linked by O—H···O bonds to form an infinite water chain along the a axis. In addition, the water molecules in the water chains donate hydrogen bonds to N atoms of L molecules, and L molecules donate C—H···O bonds to water molecules. So the water chains link all L molecules along the c axis to generate a two dimensional supramolecular layerlike structure (Fig. 2). The sheet is waved and parallel to the a,c plane (Fig. 3).
