3β-Chloro-5α-cholestan-6-one.

ABSTRACT: 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 a two-dimensional network by weak C-H⋯O hydrogen bonds. The crystal studied is a nonmerohedral twin with a refined ratio of twin components of 0.264 (3):0.736 (3).
