摘要
合成并测定了一种新的三维超分子体系——[Cd(C6H4O2N)2(H2O)4]的晶体结构.该晶体属于三斜晶系,Pī空间群,a=6.4461(13),b=6.9332(14),c=9.4411(19)魡,α=94.75(3)°,β=104.70(3)°,γ=112.08(3)°,V=370.63(13)魡3,μ=1.518mm-1,Z=1,M=428.67,Dc=1.921g/cm3,F(000)=214,λ(MOKα)=0.71073魡,最终偏离因子R1=0.0405,ωR2=0.1236.该超分子体系的基本结构单元[Cd(C6H4O2N)2(H2O)4]中,Cd处于八面体的中心;各个结构单元之间通过氢键相互连接,形成无限伸展、层状结构的三维超分子体系.
A supramolecular compand [Cd（C6H4O2N）2（H2O）4] was synthesized by the reaction of Cd（NO3）·6H2O and isonicotinic. The results of single-crystal X-ray diffraction revealed that it consists of [Cd（C6H4O2N）2（H2O）4] units in which the Cd （ Ⅱ ） ion is located in a slightly distorted octahedral center. Each unit is connedted by the OH…O hydrogen bonds to form a three-dimensional layered structure.
