The structure of pinaverium bromide (systematic name: 4-[(2-bromo-4,5-dimethoxyphenyl)methyl]-4-{2-[2-(6,6-dimethyl-2-bicyclo[3.1.1]heptanyl)ethoxy]ethyl}morpholin-4-ium bromide; C26H41Br2NO4), was determined at 110 K. It has monoclinic (P21) symmetry. It is of interest with respect to its anti-inflammatory properties. The asymmetric unit contains two independent molecules, one of which exhibits disorder of the bicyclo terminal group (occupancy factors: 0.78 and 0.22).
