(+)-3-Oxoandrost-4-ene-17β-carboxylic Acid: Catemeric Hydrogen Bonding in a Steroidal Keto Acid

A. P. J. Brunskill, R. A. Lalancette and H. W. Thompson

The title keto acid, C₂₀H₂₈O₃, forms translational carboxyl

ketone (O-H

O) hydrogen-bonding catemers [O

O 2.692 (3) Å], which follow no crystallographic axis. The cell contains two screw-related molecules having the same end-to-end orientation, each of which participates in a separate hydrogen-bonding chain.
