Abstract
The diol host compound 2,2′-bis(hydroxydiphenylmethyl)-1,1′-binaphthyl crystallised in three different polymorphic structures, and formed a series of inclusion compounds with pyridine, morpholine and benzene. Different stoichiometries were obtained by manipulating the proportions of the guests and the crystallisation temperatures. A number of these compounds are isostructural and the guests are located at fixed sites in the crystal structure. Structural similarities were interpreted via Hirshfeld surface fingerprint plots. The results of thermal analysis of one structural group were explained in terms of the host⋯guest interactions.
