The title compound, [Zn(CH3CO2)Cl(C14H14N4)]n, is a one-dimensional coordination polymer in which the ZnII ion is tetrahedrally ­coordinated by two N atoms of a bridging 1,1′-[1,4-phenyl­enebis(methyl­ene)]di-1H-imidazole ligand, an acetate O atom and a Cl atom. The Cl atom, two acetate O atoms and two acetate C atoms are located on a mirror plane. The coordination of the diimidazole ligand to the ZnII ion gives an infinite one-dimensional zigzag structure along the b-axis direction with the charge balanced by the chloride and acetate ions.

Comment top

In the field of supramolecular chemistry and crystal engineering, the design and assembly of metal-organic coordination polymers with appealing structures and properties have stimulated interests of chemists in recent years (Wang et al., 2009 and Leininger et al. 2000)). Thus far, a large number of metal-organic coordination polymers have been prepared. Herein, a new metal coordination polymer has been prepared by using a bidentate ligand.

As shown in Fig. 1, the asymmetric unit of compound was composed of a 1,4-bis((1H-imidazol-1-yl)methyl)benzene ligand (L), a divalent zinc ion, a chloride ion, and an acetate ion. The bond lengths of Zn—N, Zn—O, and Zn—Cl are consistent with those reported result (Li et al., 2008). The orgainic ligand in a trans-coordination mode to coordinate with the zinc ions by using two terminal nitrogen atoms, leading to the one-dimensional zigzag coordination polymer. The dihedral angle of the imidazol and benzene planes is 87.293 (2)°, and two the imidazol planes is parallel with the dihedral angle of 0°. The adjacent single chains are parallel along the direction of b axis, Fig. 2.

Experimental top

The title compound was synthesized referring to the reported literature (Wang et al., 2012). A mixture of Zn(OAc)2.2H2O (0.0422 g, 0.1 mmol), ZnCl2 (0.014 g, 0.1 mmol), and 1,4-bis((1H-imidazol-1-yl)methyl)benzene ligand (L) (0.024 g, 0.1 mmol), and H2O (15 ml) was sealed in 25 ml Teflon-lined stainless steel reactor and heated to 120 oC. Colorless block-shaped crystals suitable for X-ray diffraction analysis were separated by filtration with the yield of 0.031 g, 78% (based on ligand).

Refinement top

All the non-hydrogen atoms were refined anisotropically by full-matrix leastsquares calculations on F2. All H atoms (except H1a) were placed in geometrically idealized positions and treated as riding on their parent atoms with C—H = 0.93 Å, Uiso = 1.2Ueq (C) for aromatic atoms, C—H = 0.96 Å, C—H = 0.96 Å, Uiso = 1.5Ueq (C) for methyl atoms.

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.
