The five-coordinate Sn atom in the title salt, [(CH(3))(3)(C(6)H(6))N][SnBr(2)(C(6)H(5))(3)], exists in a distorted trans-C(3)SnBr(2) trigonal-bipyramidal coordination geometry. In the crystal structure no obvious hydrogen bonding is observed.
The mol-ecule of the title compound, [Sn(C(5)H(5)S)(4)], lies on a special position of site symmetry. The Sn(IV) atom shows a slightly distorted tetra-hedral coordination.
The Sn(IV) atom of the stannate anion in the title salt, (C(7)H(11)N(2))(2)[SnBr(4)(C(6)H(5))(2)], lies on a center of inversion in a tetra-gonally compressed octa-hedron. The two independent Br atoms in the anion are hydrogen-bond acceptors for the same cation.
In the centrosymmetric title compound, [Sn(4)Br(2)(C(6)H(5))(8)O(2)(OH)(2)], the four tin(IV) atoms are bridged by the hydroxo and oxo ligands, forming a ladder-like array of three edge-connected Sn(2)O(2) squares. The two independent tin atoms show distorted trigonal-bipyramidal SnC(2)O(3) and SnC(2)O(2)Br coordination geometries.
