Hydrogen bonding in dibromo[2‐(dimethyl­aminomethyl)phenyl][2‐(dimethylammoniomethyl)phenyl]tin(IV) tetra­bromo­[2‐(dimethyl­aminomethyl)phenyl]­tin(IV)

The mol­ecular structure of the title compound, [SnBr₂(C₉H₁₂N)(C₉H₁₃N)][SnBr₄(C₉H₁₂N)], consists of a dibromo­bis[2‐(dimethyl­aminomethyl)phenyl][2‐dimethylammoniomethyl)phenyl]tin(IV) cation and a tetra­bromo­[2‐(dimethyl­aminomethyl)phenyl]tin(IV) anion. As a result of strong intra­molecular N→Sn inter­actions, distorted trigonal–bipy­ramidal and octa­hedral coordination geometries are established for the metal centres of the diorganotin(IV) and monoorganotin(IV) fragments, respectively. The cation and anion are linked together by two Br⋯H contacts, while three additional similar contacts result in a dimeric fragment which repeats in a two‐dimensional supra­molecular arrangement.
