title: 3β-Acet-oxy-5α-cholestan-6-one 2-cyano-acetyl-hydrazone.
abstract: 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 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 the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the two independent mol-ecules together, generating R(2) (1)(7) and R(2) (2)(8) ring motifs.
