Abstract
Two silver cluster compounds {[Co(1,10′-phen)3]2‧[Ag8I12]} (1) and {[Co(2, 2′-bipy)3]‧[Ag10I11]‧(OH)‧3DMF‧2H2O} (2) (1,10′-phen=1,10′-phenanthroline, 2, 2′-bipy=2,2′-bipyridine) were designed and synthesized by solvent evaporation method. The two silver cluster compounds were characterized by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy, thermogravimetric analysis and X-ray powder diffraction. The crystal structures of compounds 1 and 2 were determined by X-ray crystallography diffraction. Through the electrostatic interaction between the metallic Ag cluster moiety and the metallic Co cluster moiety, form stable interlaced layered super molecular structures. In order to explore functional properties, the catalytic reduction of p-nitrophenol and electrochemical behavior of compounds 1 and 2 were explored. The results show that compounds 1 and 2 can efficiently catalyze the reduction of p-nitrophenol in the aqueous solution, and the reduction and removal rate can reach more than 90%.
