摘要：

The host molecule 2,7-dimethyltricyclo[4.3.1.0(3,8)]undecane-syn-2,syn-7-diol 1 is known to form two different structural types of lattice inclusion compound dependent on the guest molecule chosen. Guests, including 1,2-dichlorobenzene 2, have now been predicted which result in the formation of both lattice types according to the crystallisation conditions employed. Crystal structures of the ellipsoidal clathrate type: (Racemic-1)4.(1,2-Dichlorobenzene), space group I4(1)/acd; and the helical tubulate type: (Resolved-1)3.(1,2-Dichlorobenzene), space group P3(1)21 are presented. The latter polymorph is transformed into the former on heating in a sealed system.
