摘要
The title compound is a mono-thionated derivative of the diketopyrrolopyrrole red-pigment on the market. The crystal data are: C18H12N2OS, M-r = 304.37, monoclinic, P2(1)/n, a = 7.570(3) Angstrom, b = 4.869(3) Angstrom, c = 19.616(4) Angstrom, beta = 99.07(3)degrees, V = 714.0(6) Angstrom(3), Z = 2, D-x = 1.416, D-m = 1.372 Mg m(-3), graphite-monochromated CuKalpha, lambda = 1.5418 Angstrom, F(000) = 316.00, mu = 2.030 mm(-1), T = 296 K, R = 0.073 for 890 reflections. The phenyl rings are twisted out of the planar heterocyclic system by about 6.3(7)degrees. The oxygen and sulfur atoms are not entirely on the plane of the heterocyclic system, but are located slightly below and above the plane by about 0.17(1) Angstrom and 0.09(1) Angstrom, respectively. The molecules are stacked alternately (upside down) in a herringbone fashion along the b-axis.
