Further development of the general rule correlating guest space topology and guest content in polymorphs of the given inclusion compound with crystallization temperatures

Abstract

The rule correlating topology of guest space and guest content of polymorphic modifications of the given clathrate with their crystallization temperatures has been formulated by the author in 1999. Considering new polymorphic modifications of 18 host–guest complexes obtained in the past years, excellent satisfaction of the rule has been found in practically all cases. Nevertheless, two polymorphic clathrates indicate to necessity of involving specific host–guest interactions. The rule has been developed taking into account this feature and reformulated for more clarity.
