摘要:
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.
Abstract:
A new silver-8-hydroxyquinoline complex, Ag(8-HQ)2(8-HQ=8-hydroxyquinoline), is prepared from the solution reaction of 8-hydroxyquinoline and Ag2O in a mixed media of acetonitrile/water. X-ray single crystal analysis reveals that complex crystallizes in orthorhombic, space group P212121 with 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 and GOF(good-of-fit)=1.068. The molecular formula of the complex is C18H13AgN2O2. In the crystal structure of this complex, each Ag center is chelated by two 8-HQ ligands to generate a distorted parallelogram conformation, and a 1D simple parallel twin-chain-like supramolecular array is constructed by the intermocular hydrogen bond and the aromatic π-π stacking interaction. A green fluorescent emission at 522 nm for solid state and a fluorescent emission at 425 nm for solution phase are observed in this complex, respectively.
