摘　　要：以水杨醛、溴乙胺氢溴酸盐、1-正丁基咪唑为原料合成配体SN-Br,利用溶剂热法合成笼状银配合物[Ag_(4)(PPh_(3))4Br_(4)].利用X-射线单晶衍射、能谱、热重等分析方法对目标配合物进行了表征.结构分析表明:目标配合物属于正交晶系,空间群为Pcnb,晶胞参数a=18.208 nm,b=18.490 nm,c=21.117 nm,α=β=γ=90°,V=7109.37 nm_(3),Z=24,4个Ag原子和4个三重桥联的Br原子交错排布,每个Ag原子与3个Br原子配位,进一步与膦配体配位形成笼状结构.对[Ag_(4)(PPh_(3))4Br_(4)]配合物进行光催化性能测试,发现其在紫外光照射下对甲基橙溶液的降解效果良好,降解率为96.8%.The ligand(SN-Br)was synthesized from salicylaldehyde,bromoethylamine hydrobromide,and 1-n-butylimidazole,and the cage-like silver complex[Ag_(4)(PPh_(3))4Br_(4)]was obtained by hydrothemal method.The structure of the target complex was confirmed by X-ray single crystal diffraction,energy spectrum analysis,thermogravimetric analysis and other analytical methods.The structure analysis shows that the target complex is the orthorhombic system and the space group is Pcnb.The unit cell parameters are a=18.208 nm,b=18.490 nm,c=21.117nm,α=β=γ=90°,V=7109.37 nm_(3),Z=24.Four Ag atoms and four triple bridged Br atoms are arranged alternately,each Ag atom is coordinated with three Br atoms,and further coordinated with the phosphine ligand to form a cage structure.The photocatalytic performance of the[Ag_(4)(PPh_(3))4Br_(4)]complex was tested.The degradation effect of the methyl orange solution under ultraviolet light is good,and the degradation rate is 96.8%.
