Abstract

THE crystal and molecular structures of 7α-bromocholesteryl chloride, C27H44ClBr (Fig. 1), were determined by Bürki and Nowacki1 in 1956 by single crystal X-ray diffraction analysis using a combination of heavy atom, isomorphous replacement, and Patterson superposition methods. The unit cell is monoclinic, space group P21 with cell constants of a0 = 11.95 Å, b0 = 8.78 Å, c0 = 12.54 Å, β = 101.2°, and Z = 2.
