2,3,7,8,12,13-Hexahydroxy-10,15-dihydro-5H-tribenzo[a,d,g]cyclononene acetone disolvate

The title compound, C21H18O6.2C(3)H(6)O, crystallizes as a clathrate complex that includes two acetone guest molecules in a capsular assembly formed by two 2,3,7,8,12,13- hexahydroxy-10,15-dihydro-5H-tribenzo[a,d,g]cyclononene molecules. Intermolecular hydrogen-bonding and host-guest interactions define this dimeric clathrate complex, which is also part of a two-dimensional extensively hydrogen-bonded sheet involving the clathrate complex and acetone solvent molecules in the extended crystal packing.
