Abstract
Cholic acid forms inclusion compounds with acetone, methyl ethyl ketone and diethyl ketone. Crystal structures with these closely related guest molecules indicate variations in packing which result in respectively: unusual 2∶3 host: guest stoichiometry and loss of the 21 screw axis, doubling of the c axis with formation of two different channels and the usualP21 structure with 1∶1 host: guest stoichiometry.
