In the the title compound, [Co(C8H10O4)(C14H14N4)]n, the CoII atom is four-coordinated by two N atoms from two different 1,2-bis(imidazol-1-ylmethyl)benzene ligands and two carboxylate O atoms from two different cyclohexane-1,4-dicarboxylate anions in a tetrahedral coordination geometry. The resulting structure is a two-dimensional polymer with layers in the (100) plane.

1,4-H2chdc (0.5 mmol), 1,2-bix (0.5 mmol) and cobalt chloride hexahydrate (0.5 mmol) were placed in water (12 ml), and triethylamine was added until the pH value of the solution was 5.4. The solution was heated in a 23 ml Teflon-lined stainless-steel autoclave at 430 K for 5 days. The autoclave was cooled to room temperature over several hours. Purple crystals were isolated in about 38% yield.
All H atoms were positioned geometrically (C—H = 0.93 to 0.98 Å) and refined as riding, with Uiso(H)=1.2Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 flexible N-donor ligand, 1,2-bis(imidazol-1-ylmethyl)benzene is a good candidate for the construction of coordination polymers (Li et al., 2009). We report here the synthesis and structure of the title compound, composed of this ligand, cyclohexane-1,4-dicarboxylate and Co atoms.
The CoII atom is four-coordinated by two nitrogen atoms from two different 1,2-bis(imidazol-1-ylmethyl)benzene ligands and two carboxylate oxygen atoms from two different cyclohexane-1,4-dicarboxylate anions in a tetrahedral coordination geometry. The resulting structure is a two-dimensional polymer with layers in the (1 0 0) plane.
