摘要 在水热条件下,用Cu(Ⅱ)盐与邻菲罗啉(phen)进行反应,得到了三维超分子[Cu2(phen)2(H2O)4].(SO4)2(化合物1).化合物1为单斜晶系,C2/c空间群,晶胞参数:a=4.233(2)nm,b=1.3844(8)nm,c=0.7025(4)nm,β=90.230(7)°,V=4.117(4)nm3,Z=8,R1=0.0898,ωR2=0.1566.化合物1中,两个中心Cu(II)离子均以四配位模式分别形成平面四边形单元[CuN2O2]2+.配离子[CuN2O2]2+与游离的SO42-离子通过静电引力、氢键和π—π堆积作用,将化合物1构筑成三维超分子.荧光测试结果表明,化合物1在270 nm的激发波长下于450 nm处呈现出荧光发射峰. The title compound [Cu2（phen）2（H2O）4]·（SO4）2 1 was isolated from hydrothermal synthesis of Cu（II） salt and 1,10-phen.It was characterized by X-ray single-crystal diffraction,XRD,element analysis and IR.X-ray single-crystal diffraction shows 1 belongs to monoclinic system,with space group C2/c,a=4.233（2） nm,b=1.3844（8） nm,c=0.7025（4） nm,β=90.230（7）°,V=4.117（4） nm3,Z=8,R1=0.0898,ωR2=0.1566.In 1,two central Cu2＋ ions adopt four coordination mode with two N atoms and two O atoms to form [CuN2O2]2＋ planar square.The coordination units [CuN2O2]n2＋ interconnected with the free SO2-4 ions to build a3-D supramolecular network by electrostatic attraction,hydrogen bonds,π—π stacking interactions.The solid-state fluorescent property of 1 at room temperature shows compound 1 possesses a fluorescent emission band at λem=450 nm（λex=270 nm）.
