title: Cholest-5-en-7-one.
abstract: In the deca-hydro-phenanthrenone ring system of the title compound, C(27)H(44)O, the two cyclo-hexane rings adopt chair conformations, whereas the cyclo-hexene ring adopts an envelope conformation. The cyclo-pentane ring is twisted. In the crystal structure, mol-ecules are stacked along the a axis, but no significant inter-molecular inter-actions are observed.
