| Popis: | The asymmetric unit of the title compound, C30H48ClN3O, contains two molecules, A and B. In both molecules, the three cyclohexane rings in the steroid fused ring systems adopt chair conformations, while the cyclopentane rings adopt envelope and twist conformations in molecules A and B, respectively. In molecule B, the cyano group is disordered over two orientations with refined site-occupancies of 0.593 (8) and 0.407 (8). An intramolecular C—H...N interaction forms an S(10) ring in both molecules. In the crystal, molecules are linked by N—H...O, C—H...O and C—H...N interactions, resulting is chains propagating along the a-axis direction. |
