Tetraethylammonium tribromo[2-(2- acetoxystyryl)benzothiazole]platinate(II), [(C2H5)4N]-[PtBr3(C17H13NO2S)], Mr = 860.4 monoclinic, P21/c, a = 11.230 (9), b = 19.333 (4), c = 13.685 (6) A, beta = 101.06 (4) degrees, V = 2916 (4) A3, Z = 4, D chi = 1.96 g cm-3, lambda(Mo K alpha) = 0.71073 A, mu = 90.3 cm-1, F(000) = 1648, T = 296 K, final R = 0.047 for 3384 unique observed reflections. The [PtBr3(asb)]- unit has square-planar geometry about the Pt, with the asb coordinated to the Pt through the N of the thiazole ring and a Pt-N bond distance of 2.010 (8) A. The average Pt-Br distance is 2.426 (7) A. The ligand is non-planar with a dihedral angle of 22.4 (7) degrees between the benzothiazole and the acetoxybenzene rings. The dihedral angles between the platinum coordination plane and the benzothiazole and benzene rings are 85.7 (1) and 71.3 (3) degrees respectively.
