摘　　要：由于无机-有机杂化微孔晶体材料在选择性催化、分子识别和可逆性主客体分子(离子)交换等方面存在潜在的应用前景, 已经越来越引起人们的广泛注意. 传统的沸石和分子筛微孔晶体材料以硅酸盐、硅铝酸盐、磷铝酸盐和无机金属磷酸盐为骨架[1,2], 新型的无机-有机杂化微孔晶体材料用刚性和热稳定性较好的有机分子和金属离子作为结构单元[3～17].The title compound Cd(HBTCXEG) · 8(H2O) was synthesized under mild conditions and its crystal structure was determined by means of single crystal X-ray diffraction. The crystal structure was solved by direct method and refined by full-matrix least-square method. The compound crystallizes in the monoclinic system and belongs to space group P21/n with a=0. 731 1(15) nm, b = 1. 830 6(4) nm, c = 0.950 0(19) nm, β= 109. 69(3)% V=1. 197 0(4) nm3, Z = 4, Dc = 4. 832 g/cm3, Mr = 526. 72, uuuuuu = 2. 981 mm-1, F(000) = 1 716, GOF=1. 146, R=0. 095 8, Rw = 0. 276 2. Its structure revealed that coordination of HBTC ligands with Cd ions forms a 2-D network along be plane, while 4,4' -bpy as pillars uphold the 2-D network to lead to a 3-D framework along a axis.
