Tricyclo-hexyl-tin cinnamate reacts with 4,4-dimethyl-amino-pyridine hydro-bromide perbromide to form the title compound, [Sn(C(6)H(11))(3)(C(9)H(7)Br(2)O(2))], which exists as a monomeric mol-ecule with the Sn atom in a distorted tetra-hedral C(3)O coordination geometry.
The 4-nitro-cinnamate anion in the title compound, [Sn(C(7)H(7))(3)(C(9)H(6)NO(4))](n), bridges adjacent tribenzyl-tin cations into a helical chain running along the b axis. The Sn atoms in the two independent mol-ecules adopt distorted trans-C(3)SnO(2) trigonal-bipyramidal geometries. The repeat distance of the polymeric chain is b/2.
In the crystal of the title compound, C(9)H(8)Br(2)O(2), inversion dimers linked by two O-H⋯O hydrogen bonds occur. All of the carbon and oxygen atoms are disordered over two sets of sites in a 2:1 ratio.
