Abstract
Conformationally flexible 1,3,5-tris(3-methoxybenzoyl)benzene was found to form isomorphous lattice-type inclusion adducts with benzene, acetone and trimethylamine
N
-oxide (TMNO). All three inclusion complexes crystallize in the three-fold symmetric space group

molecular symmetry evident in the triaroylbenzene hosts and enclathrated guests. Inclusion complexes were not obtained when the title compound was crystallized from larger solvents or solvents lacking trigonal symmetry elements. Thus, it appears that reinforcing symmetry properties of host and guest act in tandem to afford highly symmetrical (trigonal hexagonal) clathrates.
