The Crystal Structures of 4-(1-Methylpiperidin-1-ium-1-yl)-2,2-Diphenylbutanamide Bromide and 4-(1-Methylpiperidin-1-ium-1-yl)-2,2-Diphenylbutanamide Bromide Hemihydrate

Fenpiverinium is an agent which, from a medical perspective, has anticholinergic and antispasmodic properties, with applications in the treatment of smooth muscle spasm. The crystal and molecular structures of two fenpiverinium-based crystals, namely fenpiverinium bromide and fenpiverinium bromide hemihydrate, were elucidated and explored by single-crystal X-ray diffraction.
