摘要
Molecular structures of inclusion complexes of the title host with 2,5-, 2,6- and 3,4-xylidines were determined by X-ray analysis. In addition to the relatively strong hydrogen bonds, intermolecular C-H . . . pi, N-H . . . pi and pi . . . pi interactions were found in the structures. The importance of these weak interactions is discussed in relation to the stability of the inclusion complexes.
