The salt bis(2-amino-5-methylpyridinium) hexabromostannate(IV) (C6H9N2)2[SnBr6] is monoclinic, P2 1 /c, with the following cell parameters: a=9.1636(18) Å, b=28.767(7) Å, c=16.956(17) Å, β=101.008(5)°, V=4387.5(17) Å3, Z=8, formula units. X-ray crystallography revealed that the structure can be regarded as a semi-regular three-dimensional array of anions, with pairs of cations forming layers perpendicular to b axis in the cavities between the anions. The cohesion forces that connects molecules in the organic layers are hydrophilic N⋯HCH2 and HN⋯HN hydrogen bonding as well as hydrophobic π-π stacking and CH3⋯π interactions. Cations and anions are connected via strong Br⋯H hydrogen bonding.
