cis-Bis[2-(2-acetoxystyryl)benzothiazole]dichloroplatinum(II), [PtCl2(C17H13NO2S)2], Mr = 856.7, triclinic, P1, a = 12.145 (6), b = 12.859 (4), c = 11.021 (5) A, alpha = 105.88 (3), beta = 90.64 (4), gamma = 87.64 (4) degrees, V = 1654 (2) A3, Z = 2, D chi = 1.72 g cm-3, lambda(Mo K alpha) = 0.71073 A, mu = 46.1 cm-1, F(000) = 840, T = 296 K, final R = 0.029 for 6121 unique observed reflections. The [PtCl2(asb)2] complex has square-planar geometry about the Pt, with the asb coordinated to the Pt through the N of the thiazole ring. The average Pt-N and Pt-Cl bond distances are 2.035 (1) and 2.287 (5) A. The ligand is non-planar with an average dihedral angle of 36 (3) degrees between the benzothiazole and the benzene rings. The dihedral angles between the platinum coordination plane and the benzothiazole and benzene rings are 78 (4) and 69 (7) degrees respectively. The acetoxybenzene rings in the two ligands have different orientations with respect to the olefin C atoms.
