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[Ag4(PPh3)4Br4].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=7 109.37 nm3,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[Ag4(PPh3)4Br4]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％.
Abstract
The ligand(SN-Br)was synthesized from salicylaldehyde,bromoethylamine hydrobromide,and 1-n-butylimidazole,and the cage-like silver complex[Ag4(PPh3)4Br4]was obtained by hydrothemal method.The structure of the target complex was confirmed by X-ray single crystal diffrac-tion,energy spectrum analysis,thermogravimetric analysis and other analytical methods.The structure a-nalysis 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=7 109.37 nm3,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 pho-tocatalytic performance of the[Ag4(PPh3)4Br4]complex was tested.The degradation effect of the meth-yl orange solution under ultraviolet light is good,and the degradation rate is 96.8％.
