Bupropion hydrobromide propanol hemisolvate

M. Liu, X.-R. Hu, J.-M. Gu and G.-P. Tang

Abstract: The title compound {systematic name: N-[1-(3-chlorophenyl)-1-oxopropan-2-yl]-tert-butanaminium bromide propanol hemisolvate}, C13H19ClNO+·Br-·0.5C3H8O, crystallizes with two independent bupropion hydrobromide ion pairs and a solvent 1-propanol molecule in the asymmetric unit. In both molecules, the expected proton transfer from HBr to the amino group of the bupropion molecule is observed, and intra- and intermolecular N-H...Br hydrogen-bond interactions are formed. These interactions link the molecules into hydrogen-bond dimers. The side chains of the two cations have slightly different orientations. The 1-propanol solvent molecule is linked to a bromide ion by an O-H...Br hydrogen bond.
