Bis[4-(dimethyl-amino)pyridinium] tribromidochloridodimethyl-stannate(IV)

The Sn(IV) atom in the title salt, (C(7)H(11)N(2))(2)[SnBr(3)(CH(3))(2)Cl], lies on a center of inversion in a tetra-gonally compressed octa-hedron; two independent Br atoms share the same site as two independent chlorine atoms so that the anion effectively has one Cl and three Br atoms. The occupancies of the Br atoms are 0.721 (1) and 0.779 (1), and those of the Cl atoms are 0.279 (1) and 0.221 (1). The crystal structure involves N-H⋯halogen hydrogen bonds.
