The title tetracyclic steroidal compound, C27H46O2·0.5H2O, crystallized as a monohydrate with two independent molecules (1and2) in the asymmetric unit. In both molecules, the conformations of the three cyclohexane rings (A,BandC) are chair, half-chair and chair, respectively. The fourth ring,D, has a twisted conformation on the bond linking theDandCrings. The crystal structure is stabilized by hydrogen bonding with the two independent molecules being linked through the solvent water moleculeviavarious O—H...O hydrogen bonds, forming layers parallel to (-101).
