Crystallographic data for 1： C12H8O16Cu3, Mr = 598.80, orthorhombic, Pbcn, a = 8.4378（6）, b = 10.0396（7）, c = 17.6799（12）A, V = 1497.70（18）A^3, Z = 4, De = 2.656 g/cm^3, μ = 4.327 mm^-1, F（000） = 1180, R = 0.0431 and wR = 0.0964 for 1075 observed reflections （I 〉 2σ（I））. X-ray crystal structural analysis revealed that the mellitate anions behave as the bridging ligands and link eight copper atoms repeatedly to form a novel three-dimensional metal-organic coordination polymer with two different rhombic tunnels in the solid-state structure.展开更多
