Poly[[μ(2)-1,4-bis(imidazol-1-ylmethyl)benzene]bis(μ(4)-cyclohexane-1,4-dicarboxylato)dicobalt(II)]
In the title compound, [Co(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), the two Co(II) atoms are both five-coordinated by four carboxylate O atoms, derived from two different cyclohexane-1,4-dicarboxylate (chdc) ligands, and an N atom, derived from one end of a 1,4-bis(imidazol-1-ylmethyl)benzene...

Sumario: | In the title compound, [Co(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), the two Co(II) atoms are both five-coordinated by four carboxylate O atoms, derived from two different cyclohexane-1,4-dicarboxylate (chdc) ligands, and an N atom, derived from one end of a 1,4-bis(imidazol-1-ylmethyl)benzene molecule (1,4-bix), in a distorted square-pyramidal environment. Each end of the chdc ligand links pairs of Co(II) atoms into a paddle-wheel assembly, i.e. Co(2)(O(2)CR′)(4); these are connected into rows because of the bridging nature of the chdc ligands, and the rows are further connected into a two-dimensional layer through the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions were discerned for the –CH(2)(C(6)H(4))CH(2)– residue, with the major component having a site-occupancy factor of 0.512 (9). |
