โฆ Synopsis
Crystalline organic inclusion compounds are currently of considerable interest to solid state chemists and physicists in view of the wide range of important physicochemical properties associated with them. The urea inclusion compounds represent one classic example of such solids, and this article is focused on the urea inclusion compounds containing alkane guest molecules. Structural and dynamic properties of these solids have been probed using a wide range of experimental and computational techniques, and the aim of the article is to assess the current level of understanding of these properties. The importance of adopting a multidisciplinary experimental and computational approach towards investigating the properties of these solids is emphasized. 1993 Academic Press, Inc.
