摘要
A new Cu(Ⅰ) coordination polymer(CP) formulated as [Cu2(L)(CN)2]n(1, L =1,1′-bis(5,6-dimethylbenzimidazole)methane) was synthesized, in which the cyanide anions were generated in situ by the cleavage of C–C bond of acetonitrile under hydrothermal conditions. CP 1 was characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. It crystallizes in the orthorhombic system, Pccn space group, with a = 10.314(3), b = 20.966(7), c =9.432(3)?, V = 2039.5(11)?3, Z = 4, C21 H20 Cu2 N6, Mr = 483.51, Dc = 1.575 g×cm^-3,μ= 2.105 mm-1 and F(000)= 984, the final R = 0.0608 and wR = 0.1942 for 1226 observed reflections with Ⅰ> 2s(Ⅰ)for the CP 1. The CP 1 possesses a 2D {63} layer structure which is composed of Cu(Ⅰ) centers bridged by L and CN– ligands. The thermal stability and luminescence properties of CP 1 are discussed in detail. The complex also displays a remarkable activity for the degradation of methyl orange by hydrogen peroxide in a Fenton-like process.
