The reaction of 4-pyridinecarboxylic acid (Hpyca) and Ag2O under hydrothermal condition with 1:1square channels along the a axis. X-ray single crystal structural analysis reveals that its crystallizes in monoclinic,space group P21/c with a=0.369 34(5), b=1.217 83(17), c=1.523 9(2) nm,β=90.100(2)°, V=0.685 44(16) nm3, Z=4,The fluorescence spectrum of the coordination polymer exhibits intense emission at 524 nm when excited at 469nm in solid state at room temperature.%以1:2物质的量之比的Ag2O和Hpyca(异烟酸)为原料,在水热条件下得到了一个新颖的三维配位聚合物[Ag(pyca)]n·nH2O(1).单晶X-射线结构分析表明,1晶体属于单斜晶系,P21/c空间群,1的空间堆积在沿a轴方向形成了大小为0.66 nm×0.84 nm的方形孔洞.1的固体室温荧光测试结果表明,在波长为469 nm的光激发下于524 nm处出现强烈的荧光发射.
