Popis: | The structure of the polymeric title compound, [Ni2(C8H10O4)2(C14H14N4)]n, features a five-coordinate NiII centre defined by four carboxylate O atoms from two different cyclohexane-1,4-dicarboxylate (chdc) ligands and an N atom from one end of a 1,4-bis(imidazol-1-ylmethyl)benzene (1,4-bix) molecule. The NO4 coordination geometry is distorted square-pyramidal with the N atom in the apical position. Each end of the chdc ligand links pairs of NiII atoms into a paddle-wheel assembly, i.e. Ni2(O2CR′)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 –H2C(C6H4)CH2– residue. |
