Abstract

The complete crystal structures of two as-made zeolites with the ITQ-52 structure (IFW framework type), where an alkylphosphonium and an aminophosphonium dications have been used as their respective organic structure-directing agents, have been solved by three-dimensional electron diffraction. Both organic cations have also been located within the 10-ring that connects the cavities of the IFW framework using the diffraction data.

利用三维电子衍射测定人造沸石 ITQ-52 的结构

通过三维电子衍射解决了两种 ITQ-52 结构（IFW 框架类型）沸石的完整晶体结构问题，这两种沸石分别使用了一种烷基膦和一种氨基膦阳离子作为各自的有机结构引导剂。利用衍射数据还确定了这两种有机阳离子在连接 IFW 框架空腔的 10 环内的位置。

期刊介绍： Microporous and Mesoporous Materials covers novel and significant aspects of porous solids classified as either microporous (pore size up to 2 nm) or mesoporous (pore size 2 to 50 nm). The porosity should have a specific impact on the material properties or application. Typical examples are zeolites and zeolite-like materials, pillared materials, clathrasils and clathrates, carbon molecular sieves, ordered mesoporous materials, organic/inorganic porous hybrid materials, or porous metal oxides. Both natural and synthetic porous materials are within the scope of the journal. Topics which are particularly of interest include: All aspects of natural microporous and mesoporous solids The synthesis of crystalline or amorphous porous materials The physico-chemical characterization of microporous and mesoporous solids, especially spectroscopic and microscopic The modification of microporous and mesoporous solids, for example by ion exchange or solid-state reactions All topics related to diffusion of mobile species in the pores of microporous and mesoporous materials Adsorption (and other separation techniques) using microporous or mesoporous adsorbents Catalysis by microporous and mesoporous materials Host/guest interactions Theoretical chemistry and modelling of host/guest interactions All topics related to the application of microporous and mesoporous materials in industrial catalysis, separation technology, environmental protection, electrochemistry, membranes, sensors, optical devices, etc.
