The molecular structure of the title compound, showing the atom labeling and displacement ellipsoids drawn at the 40% probability level. Disordered atoms are drawn with 40% transparency and A-labeled for the (R)-isomer [s.o.f. = 0.624 (2)] and B-labeled for the (S)-isomer [s.o.f. = 0.376 (2)]. The ethanol solvate molecule is omitted for clarity. |
