摘要
本文以季戊四胺与2-醛基吡咯合成了2,4,8,10-四氮螺[5.5]-3,9-二(2-吡咯基)十一烷(1),并通过单晶X-射线衍射方法进行了表征。该晶体属于三斜晶系,空间群为:P-1,相关晶胞参数为:a=8.386(2),b=10.541(3),c=0.779(3),α=87.274(10)°,β=87.769(10)°,γ=84.387(10)°,V=946.6(4)3.该化合物晶体结构中包含了1个2,4,8,10-四氮螺[5.5]-3,9-二(2-吡咯基)十一烷分子和4个水分子,这些水分子与吡咯环上的氮原子之间通过氢键连接成无限延伸的一维超分子链,同时这些氢键进一步将一维超分子链连接成为二维的超分子网络结构。
A compound 3,9-di ( 1H-pyrrol-2-yl ) -2,4,8,10-tetraazaspiro [ 5.5 ] undecane was synthesized andstructurally characterized by single crystal X-ray diffraction structural determination. Crystal data: a = 8. 386 (2) А, b=10.541(3)А, c=0.779(3)А, a=87.274(10)°,β
= 87.769(10)°, γ=84.38 7(10)°,V=946.6 (4) А^3. The compound is constitute of 3,9-di ( 1 H -pyrrol -2-yl) -2,4,8,10-tetraaz- aspiro [ 5.5 ] undecane and four water molecules, The water molecules and the N atoms from the pyrrol rings of 3,9-di( 1H- pyrrol-2-yl) -2, 4,8,10-tetraazaspiro [ 5.5 ] undecane are linked into one-dimensional supramolecular chain, and the chain structure further forms two-dimensional supramolecular network structure by intermolecular hydrogen bonds.
