Dipyridinium tribromidochloridobis(4-chloro-phen-yl)stannate(IV)

The tin atom in the substituted ammonium stannate(IV), (C(5)H(6)N)(2)[SnBr(3)(C(6)H(4)Cl)(2)Cl], lies on a center of symmetry in a distorted octa-hedral coordination geometry. Each independent halogen site is occupied by bromine and chlorine anions in an approximate 3:1 ratio. The pyridinium cation forms a hydrogen bond to only one of the halogen atoms.
