Abstract
In the title compound, (C7H11N2)2[SnBr4(C6H4Cl)2]·C6H4BrCl, the SnIV atom in the tetrabromidobis(4-chlorophenyl)stannate(IV) anion lies on a centre of inversion. The distances between the 4-(dimethylamino)pyridinium N atom and the Br atoms of the anion are 3.450 (2) and 3.452 (2) Å, suggesting weak hydrogen bonding. The 4-bromochlorobenzene solvent molecule, which is a bromination by-product from the reaction, is disordered about a twofold rotation axis with approximately equal occupancy.
