The SnIV atom of the stannate anion in the title salt, (C7H11N2)2[SnBr4(C6H5)2], lies on a center of inversion in a tetragonally compressed octahedron. The two independent Br atoms in the anion are hydrogen-bond acceptors for the same cation.
The molecule of the title compound, [Sn(C5H5S)4], lies on a special position of site symmetry. The SnIV atom shows a slightly distorted tetrahedral coordination.
The five-coordinate Sn atom in the title salt, [(CH3)3(C6H6)N][SnBr2(C6H5)3], exists in a distorted trans-C3SnBr2 trigonal-bipyramidal coordination geometry. In the crystal structure no obvious hydrogen bonding is observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
