摘要： 从CH3NH2-SiO2-H2O凝胶中以水热法生长出ZSM-39单晶,在Enraf-NoniusCAD-4四圆衍射仪上收集衍射强度,进行结构测定。晶体属空间群Fd3m,a=19.4028Å。最后偏离因子R=0.055。结构分析表明:甲胺分子无序分布于十六面体笼中,其碳原子位于笼的中心。胺基可提供氢原子与十六面体笼的氧原子形成氢键,从而体系内能降低,更有利于单晶的生成。

Abstract: ZSM-39 single crystals were hydrothermally grown from CH3NH2-SiO2-H2Ogel system. Its structure was determined on an Enraf-Nonius CAD4 diffractometer.The space group is Fd3m, with α= 19.403(3)Å. Final Rfactor is 0.055. The. methylamine molecules are located in the 16-hedra(hexakaidecahedra) in disorder.The carbon atom is sited on center of 16-hedron. The system is stabilized.
