Crystal and molecular structure of a steroidal spirocyclic lactone, C29H34O4

摘要

The X-ray crystal structure of the title compound, as crystallized from methanol-methylene chloride was determined. The asymmetric unit contains two steroid molecules, which differ primarily in the orientation of the aromatic rings of the benzyl ethers. The title compound crystallizes in the noncentrosymmetric space group P2( 1), with a = 7.558(2), b = 16.673(3), c = 18.735(4) Angstrom, beta = 97.610(10)degrees, and D-calc = 1.268 g cm(-1) for Z = 4.
