Abstract The compound 9-benzamido-6,7,8,9,10,11-hexahydro-5,9:7,11-dimethano-5H-benzocyclononen-7-ol,3, has been prepared, and found to crystallise as inclusion complexes ( 2 ·G where the guest G is ethyl acetate or carbon tetrachloride. The host molecule contains a benzo group as part of a rigid polycyclic framework, on which there are hydroxy and benzamido substituents. The crystal structure of the complex with CCl4 contains the host molecules hydrogen-bonded in layers, with the CCl4 molecules trapped between the layers. Two types of host-host hydrogen bonds, OH to amide carbonyl O, and amide NH to hydroxyl O, maintain the host layers. The benzo groups protrude normal to these host layers, and six such groups provide the closest surroundings of the CCl4, which is constrained to two disordered orientations at the one location. This is a layer clathrate structure.
