Interpenetrating inclusion lattices: Comparison of the Β-hydroquinone and ellipsoidal clathrate structures

Crystallization of 2,7-dimethyltricyclo[43.1.13,8]undecane-syn-2,syn-7-diol 2 from acetonitrile or dichloro-methane yields the compounds (2)4-(guest) in space group 141/acd which are further examples of the ellipsoidal clathrate structure. Both enantiomers of 2 are linked through (O-H)4 cycles of hy...

Description
Summary:Crystallization of 2,7-dimethyltricyclo[43.1.13,8]undecane-syn-2,syn-7-diol 2 from acetonitrile or dichloro-methane yields the compounds (2)4-(guest) in space group 141/acd which are further examples of the ellipsoidal clathrate structure. Both enantiomers of 2 are linked through (O-H)4 cycles of hydrogen bonds to form a three-dimensional sublattice. Two inversion related sublattices interpenetrate thereby generating a superlattice with guest-occupied voids situated between the two individual sublattices. The two X-ray structures are compared and contrasted with that of Powell’s (hydroquinone)3 (SO2) clathrate compound.
