摘要：Using transition-metal-complex cation as the structure-directing agent, a novel one-dimensional(1D) iodoargentate-based hybrid, namely, {[Co(2,2’-bipy)3]2(Ag7I11)·3H2O}n(1) has been synthesized and structurally characterized. The interesting 1D(Ag7I11)n4n- chain of 1 is constructed from a heptameric Ag7I13 secondary building unit, in which abundant argentophilic interactions can be observed. Intermolecular C–H···π among [Co(2,2’-bipy)3]2+ cations and C–H···I interactions between [Co(2,2’-bipy)3]2+ cations and(Ag7I11)n4n- chains contribute to the formation of a 3D network. The optical gap(2.58 eV) based on UV-Vis diffuse-reflectance measurement suggests the semiconductor nature of 1, which implies an efficient photocatalytic degradation activity on organic pollutants under visible light irradiation. As expected, 1 exhibits photocatalytic activity for the degradation of rhodamine B. The luminescence property was also studied.
