Crystal structure of bis(3-bromomesityl)(quinolin-1-ium-8-yl)boron(III) tribromide
The title compound, C27H26.82BBr2.18N+·Br3−, is a cationic triarylborane isolated as its tribromide salt. The aryl substituents include a protonated 8-quinolyl group and two 3-bromomesityl groups. The molecule was prepared on combination of 3:1 Br2 and dimesityl(quinolin-8-yl)borane in hexanes. The refinement of the structure indicated a degree of `over-bromination' (beyond two bromine atoms) for the cation. There are two tribromide ions in the asymmetric unit, both completed by crystallographic inversion symmetry.
