Abstract
The Sn atom in the title salt, (C7H11N2)2[SnBr4.67Cl1.33], lies on a center of symmetry within an octahedron of disordered halogen atoms. The three independent halogen atoms are each a mixture of bromine and chlorine atoms [with site occupancies for bromine of 0.614 (1), 0.831 (1) and 0.888 (1)]. An N—H⋯ hydrogen bond is present.
