摘要：

Four Ag-based coordination polymers, Ag-4(H2O)(2)(npth)(2) (1), Ag-4(epyz)(2)(npth)(2) (2), [Ag(pyz)(Hnpth)]center dot H2O (3) and Ag(epyz)(0.5)(Hnpth) (4) (H(2)npth = 3-nitrophthalic acid, pyz = pyrazine, epyz = 2,3,5,6-tetramethylpyrazine), have been synthesized by ultrasonic or hydrothermal reactions of Ag(I) salts with H2npth and various pyrazine derivatives ligands. Compound 1 presents a 2D 4(4)-sql network with Ago units, and compound 2 features novel cage-like Ag-8 SBUs (secondary building unit), which are linked by epyz ligands to form a 3D framework. Compound 3 shows a 1D chain and compound 4 exhibits a 2D coordination polymer construction. The photocatalytic properties for the degradation of organic dye molecules have been examined, and the experiments show that compound 3 has a good degradation effect to Rhodamine B.
