Conformational studies. Part 8. Crystal and molecular structure of 17β-iodoacetoxy-4,4-dimethylandrostan-5-en-3-one

Abstract

Crystals of the title complex (2) are monoclinic, space group P2₁, a= 6.394(2), b= 11.303(4), c= 15.566(4)Å, β= 92.92(2)°, Z= 2. The structure has been refined by full-matrix least-squares calculations to a final R of 0.046 for 1 065 observed reflections. The conformations of the rings are: A, skewed boat; B, half-chair; C, chari; and D, half-chair distroted towards a C(13) envelope.
