Abstract
The ring conformation of the title compound, 3 alpha,4 beta-dihydroxy- 5 alpha-androstan-17-one, C19H30O3, is similar to that of the 5 beta-e pimer except for the trans A/B ring junction and the geometry of ring D, which adopts a slightly deformed 13,14-half-chair conformation inst ead of the more common 14 alpha-envelope conformation. The molecules a re linked together by a two-dimensional network of hydrogen bonds invo lving the carbonyl and hydroxyl groups.
