The structure of 17β-bromacetoxy-9β, 10α-androst-4-en-3-one has been determined by three-dimensional X-ray crystallographic methods. The crystals of the restrosteroid belong to the orthorhombic space group P212121 with four molecules per unit cell. The cell constants are a = 11.32 Å, b = 13.71 Å and c = 12.52 Å. The absolute configuration of the molecule has been determined by the anomalous dispersion method. Bond length, bond angles and distances of atoms from ‘best planes’ are given. Ring A represents a distorted half-chair, ring B and C a chair and ring D an envelope conformation. The molecule shows, contrary to normal 9α, 10β-steroids, a bent shape.
