摘要：

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) angstrom, b = 28.767( 7) angstrom, c = 16.956(17) angstrom, beta = 101.008( 5)degrees, V = 4387.5(17) angstrom(3), 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 center dot center dot center dot HCH2 and HN center dot center dot center dot HN hydrogen bonding as well as hydrophobic pi-pi stacking and CH3 center dot center dot center dot pi interactions. Cations and anions are connected via strong Br center dot center dot center dot H hydrogen bonding.
