摘要：
The steroid 3‐Methoxy‐estra‐1,3,5(10)triene‐16αBr,17αOH crystallizes in the orthorhombic space group P 212121 with lattice constants a = 30.653(5) Å, b = 9.039(2) Å, c = 6.098(1) Å. The single molecule has an intramolecular OH… Br interaction. Intermolecular interactions are only of van der Waals type. Ring A is nearly planar, ring B has a nearly half chair conformation, ring C has a chair conformation and ring D an envelope conformation. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
