无机-有机混合POSS纳米粒子的晶体结构和形态，由硅和氧的无机核和烷基的外部有机附着物组成，已经使用X射线衍射和电子显微镜进行了研究。这些分子自组装形成六边形堆积结构。烷基连接物容纳在六方晶格的间隙内。这些结果对我们理解聚合物-POSS纳米复合材料（例如通过共聚形成的材料）中的无序具有影响。
The crystal structure and morphology of inorganic−organic hybrid POSS nanoparticles, consisting of an inorganic core of silicon and oxygen and outer organic attachments of alkyl groups, has been studied using X-ray diffraction and electron microscopy. These molecules self-assemble to form a hexagonally packed structure. Alkyl attachments are accommodated within the interstices of the hexagonal lattice. The results have implications for our understanding of the disorder in polymer−POSS nanocomposite materials such as those formed by copolymerization.
