Solid-state stereochemistry of (-)-scopolamine hydrobromide sesquihydrate, a new polymorph of the anticholinergic drug.


The solid-state structure of (-)-scopolamine hydrobromide sesquihydrate was determined by single-crystal X-ray diffraction analysis at low temperature. (Nr,C alpha-S)-(-)-Scopolamine hydrobromide sesquihydrate gives crystals belonging to the tetragonal space group P4(3)2(1)2, and at 180 K: a = 11.870(4), c = 26.193(3) A, V = 3691(1) A3, Z = 8, R(F) = 0.062… (More)
