Acta Crystallogr E Crystallogr Commun. 2015 Jan 10;71(Pt 2):o92-3. doi: 10.1107/S2056989014028278. eCollection 2015 Feb 1.

Abstract

In the title compound, C39H58O4, the steroid rings A and C adopt a chair conformation, while ring B adopts a half-chair conformation, and ring D has an envelope conformation, with the methyl-substituted C atom as the flap. In the crystal, mol-ecules pack within layers parallel to (100), with their long axis parallel to the [101] direction. Adjacent layers are linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional framework.
