Abstract
The crystal structure of the title compound [4,17(20)-(cis)-pregnadiene-3,1 6-dione, C21H28O2] shows that the two molecules in the asymmetric unit have similar conformations. The fused-ring system contains one sofa, two chairs and one envelope. Weak intermolecular C-H . . .O hydrogen bonds, together with van der Waals interactions, stabilize the structure.
