COMPLEXATION WITH DIOL HOST COMPOUNDS .11. STRUCTURES AND THERMAL ANALYSES OF THE INCLUSION-COMPOUNDS OF 4,4'-BIS(DIPHENYLHYDROXYMETHYL)-BIPHENYL, C38H30O2, WITH ACETONE, ACETOPHENONE, 1,4-DIOXANE AND P-XYLENE

Structures of the inclusion compounds of 4,4'-bis(diphenylhydroxymethyl)biphenyl with acetone (1), acetophenone (2), 1,4-dioxane (3) and p-xylene (4) have been determined.

Depending on the host-guest interaction, they are H-bonded coordinatoclathrates in the case of 1-3 and a true clathrate type of inclusion compound in the case of 4 with H -bonded tetramer clusters of host molecules forming the inclusion matrix. The thermal decompositions of the compounds have been studied. Compound 1 contains acetone molecules in two different binding states, one being more strongly bound than the other giving two individual endotherms. Phase transitions before the melting point occur in compounds 1, 3 and 4. Compound 2 shows no melting point because of dissolution of the host compound in the released guest.
