Organic complexes were formed by montmorillonite arid four types of amines molecules. Using the X-ray cliffaction technique,basing on the theoretic structure of organic molecules, the arrangements of amines molecules in the interlayer space of montmorillonite were analyzed.Diethylenetriamine and triethylanequtiamine ions lied in montmorillonite interlayer by a single state supine. Aniline and P-nitroaniline ions existed in montmorillonite interlayer by perpendicular to the silicate layers.%4称种胺类分子与蒙脱石形成有机复合体.用X-射线粉晶衍射仪对蒙脱石有机复合体的层间域特征进行表征,根据有机分子理论结构,对这4种有机物在层间的分布状态进行推测,二乙三胺、三乙四胺分子以单层平躺状居于蒙脱石层间,苯胺和对硝基苯胺是以垂直于硅酸盐层的方式存在于蒙脱石层间.
