17-Oxo-5-hydroxyandrostan-3-yl acetate

The title compound, C21H32O4 crystallizes in a triclinic unit cell, which is very unusual for steroids. The asymmetric unit contains two independent mol­ecules with almost identical geometry, although they are slighly twisted in opposite directions. These mol­ecules form a dimer inter­connected via hydrogen bonds. Both mol­ecules have a cis A/B ring junction characteristic of a 5β-configuration, but differ in the orientation of their hydroxyl groups.
