Nodal equivalence of (O–H)6 and aromatic rings: a supramolecular cousin of Dianin's compound and β-hydroquinone1,2

Abstract

The simple dialcohol endo-4,endo-8-dimethylbicyclo[3.3.1]nonane-endo-2,endo-6-diol 2 yields inclusion compounds (diol)3.(guest) from nearly all recrystallisation experiments. These crystals have a hydrogen bonded network structure in cubic space group Ia[3 with combining macron], in which the disordered guest molecule occupies a spherical cage enclosed by eight (O–H)6 cycles positioned at the corners of a cube. Comparison of this structure with the inclusion crystals formed by Dianin's compound 1, and the β-form of hydroquinone 3, reveals familial supramolecular behaviour between the three cases. The nodal relationship of their (O–H)6 cycles or aromatic rings creates allied crystal engineering assemblies despite their dissimilar molecular structures.
