(6R*,16R*)-9,14-Dihydro-6-methyl-6,16-methano-6H,16H-[2,4]benzothiazepino[3,4-d][1,3,5]benzoxadiazocine hydrobromide dimethylformamide hemisolvate

Abstract

The title compound, C(19)H(19)N(2)OS(+).Br(-).0.5C(3)H(7)NO, is an oxygen-bridged phenylpyrimidine derivative in which the heterocyclic ring is protonated, the positive charge being dispersed over both of the N atoms. Both molecules in the asymmetric unit exist in an identical conformation, which consists of a central planar portion with the two terminal phenyl rings protruding from the same side of the plane. One of the independent molecules forms a strong hydrogen bond with the bromide anion, while the other is hydrogen bonded to the dimethylformamide solvent molecule.
