Complexation with hydroxy host compounds. Part 1. Structures and thermal analysis of a suberol-derived host and its host–guest complexes with dioxane and acetone

The title host compound, 10, 1r1 dihydro-5-pheny-5H-dibenzo[a,d]cyclohepten-5-ol 1, cystallizes in the non-porous α-phase without hydrogen bonding. The β-phases of its dioxane 2 and acetone 3 complexes are stabilized by hydrogen bonds between host and guest. Thermal analysis of the two inclusion compounds gives qualitative correlation with their structures and a relative measure of their stabilities.
