In the title compound, the Br atom is [beta]-equatorially oriented. The six-membered rings (A, B, C and F) have the expected chair conformations. The D-ring conformation is midway between a 14[alpha]-envelope and a 13[beta],14[alpha]-half-chair, and the E-ring conformation is midway between an O2[alpha]-envelope and a C21[beta],O2[alpha]-half-chair. The packing of the molecules is assumed to be mainly dictated by van der Waals forces. The closest intermolecular contact between non-H atoms is 3.300(9)Å.
