3β-Chloro-6-[2-(2-cyanoacetyl)hydrazin-1-ylidene]-5α-cholestane
The asymmetric unit of the title compound, C(30)H(48)ClN(3)O, contains two mol-ecules, A and B. In both mol-ecules, the three cyclo-hexane rings in the steroid fused ring systems adopt chair conformations, while the cyclo-pentane rings adopt envelope and twist conformations in mol-ecules A and B, respectively. In mol-ecule B, the cyano group is disordered over two orientations with refined site...

The asymmetric unit of the title compound, C(27)H(45)ClO, consists of two crystallographically independent mol-ecules. In both mol-ecules, the three cyclo-hexane rings in the steroid fused-ring systems adopt chair conformations, while the cyclo-pentane ring adopts a half-chair conformation in one mol-ecule and an envelope conformation in the other. In the crystal, the mol-ecules are linked into...

The asymmetric unit of the title compound, C(32)H(51)N(3)O(3), consists of two crystallographically independent mol-ecules, A and B; the 2-methyl-pentane group of mol-ecule A and the propane group of mol-ecule B are each disordered over two sets of sites, with refined site-occupancies of 0.825 (5):0.175 (5) and 0.630 (18):0.370 (18), respectively. In both mol-ecules, the three cyclo-hexane ring...
