16α-Bromo-17β-hydr-oxy-5α-androstan-3β-yl acetate.

The title compound, C(21)H(33)BrO(3), an inter-mediate in the synthesis of the neuromuscular blocking agent rocuronium bromide, contains two independent mol-ecules in the asymmetric unit, which have almost identical geometries: in both mol-ecules, the steroidal rings A, B and C have slightly flattened chair conformations and ring D assumes a half-chair conformation. In the crystal, O-H⋯O hydrogen bonds and weak C-H⋯O and C-H⋯Br inter-actions help to establish the packing.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)are estimated using the full covariance matrix. The cell e.s.d.'s are takeninto account individually in the estimation of e.s.d.'s in distances, anglesand torsion angles; correlations between e.s.d.'s in cell parameters are onlyused when they are defined by crystal symmetry. An approximate (isotropic)treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc, and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
