摘要
<正> Bishop开发的主体化合物1,6-二甲基-1,6-二羟基二环[3,3,1]壬烷可与乙酸乙酯等形成包结物~[1,2],柏木醇通过氢键作用可与酚类化合物形成包结物~[3].比较上述两个主体分子的结构可知,其相似之处在于它们都是桥环化合物,且具有近似球状的分子结构.考虑到六次甲基四胺也是一个球状桥环化合物,且具有与客体分子形成氢键的条件,故它与酚类化合物的包结现象也有助于氢键共晶现象的研究~[4].
This paper reports that the host species hexamethylenamine forms channel-type inclusion compounds with phenol type compounds,such as p-nitrophenol,catechol,resorcinol,hydroquinone,and p-hydroxybenzaldehyde.Their molar ratios(host/vip)are1:l,1:2,1:1,1:1 and 1:2 respectively,and melting points are 144~145℃,164℃(sub.),203℃(sub.),198℃(sub.)and 116~118℃ in the same sequence.The result of X-ray diffraction shows that the crystal of inclusion compound formed by the title host and p-nitrophenol belongs to triclinic system space group P1.The parameters are a=0.5899(1)nm,b=0.7056(1)nm,c=2.5186(11)nm,α=87.53(3)°,β=96.71(3)°,γ=90.0(2)°,Z=2.Because of the presence of random water molecules in the inclusion compound crystalline,R=0.138.The results of X-ray diffraction and IR of other inclusion compounds are also given.
