Abstract
The asymmetric unit of the title compound, C19H28O3, contains two independe
nt molecules with almost identical geometry. The molecules have a planar 5
alpha configuration as a result of a trans-A/B junction of the rings. The c
ompound crystallizes in a triclinic cell, which is unusual for steroids. Th
e molecules are linked head-to-tail via hydrogen bonds between the ring A h
ydroxyl group and the ketone group of ring D, forming two independent chain
s running along the c axis.
