Abstract:

8-羟基喹啉(8-HQ)与Ag2O在乙腈/水混合溶剂中反应可获得银-8-羟基喹啉配合物(Ag(8-HQ)2). X-射线单晶衍射分析表明,配合物晶体属正交晶系P212121空间群,分子式为C18H13AgN2O2,Mr=397.17.其晶体学参数:a=0.724 25(1)nm,b=1.049 70(2)nm,c=1.895 12(3)nm,Z=4,Dc=1.831 g?cm-3,R=0.036 6,Rw=0.097 8,拟合优度(GOF)为1.068.在其晶体结构中,每个Ag与两个8-HQ配体螯合构成畸变平面四方构型,通过分子间氢键和π-π堆积作用组成并行的一维超分子孪生链结构.固相和溶液相的配合物可分别于522 nm和425 nm处观察到荧光发射.
