In the trigonal CCl4quasiracemic clathrate, space group R3, formed from host components S-(-)-Dianin’s compound, 4, and its (+)-2R,4R 2-nor methyl analogue, 2, the unprecedented complete ordering of a C-Cl bond of the guest with respect to the c-axial direction and the participation of an unexpected host conformation is reported for the first time.

Total CCl4 guest alignment in a quasiracemic clathrate closely related to Dianin’s compound
Abstract
Single crystal X-ray analysis at 100 K reveals that in the trigonal CCl4quasiracemic clathrate, space group R3, formed from host components S-(−)-Dianin’s compound and its (+)-2R,4R 2-nor methyl analogue there is an unprecedented complete ordering of a C–Cl bond of the guest with respect to the c-axial direction. In this clathrate and that formed from the (+)-2R,4R and (+)-2R,4S epimers the participation of an unexpected host conformation is reported for the first time.
