Abstract: A novel complex-[Cu5(C10H7N2O2)4(SO4)2(N3)(H2O)2]n was prepared under hydrothermal condition. The structure of the complex was determined by single crystal X-ray diffraction analysis. The crystal is of monoclinic system,space group C 2/m with a=17.857(8) 姒,b=19.720(9) 姒, c=7.923(4) 姒, β=106.571(6)°, V=2 674.13(2) 姒3, Z=1, Dc=5.475 g·cm-3,F(000)=4 186, wR=0.080. In the molecular structure of [Cu5(C10H7N2O2)4(SO4)2(N3)(H2O)2]n,two crystallographically independent Cu(Ⅱ) ions with different coordination environments were observed, the center Cu(Ⅱ) atom was six coordinated by four O atoms of the ligand(L) and two O atoms of water molecules to form a distorted octahedral geometry.The crystal has good fluorescence property.
