Bottom Line: Each end of the chdc ligand links pairs of Ni(II) atoms into a paddle-wheel assembly, i.e. Ni(2)(O(2)CR')(4).These are connected into rows owing to the bridging nature of the chdc ligands, and the rows are connected into a two-dimensional grid via the 1,4-bix ligands.Two positions of equal occupancy were discerned for the -H(2)C(C(6)H(4))CH(2)- residue.

ABSTRACT
The structure of the polymeric title compound, [Ni(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), features a five-coordinate Ni(II) centre defined by four carboxyl-ate O atoms from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands and an N atom from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecule. The NO(4) coordination geometry is distorted square-pyramidal with the N atom in the apical position. Each end of the chdc ligand links pairs of Ni(II) atoms into a paddle-wheel assembly, i.e. Ni(2)(O(2)CR')(4). These are connected into rows owing to the bridging nature of the chdc ligands, and the rows are connected into a two-dimensional grid via the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions of equal occupancy were discerned for the -H(2)C(C(6)H(4))CH(2)- residue.
