Abstract
C13H14N2OS, Mr=246, is monoclinic, P21/c, with a=7.214(1), b=8.935(5), c=20.243 (6) Å, β=99.42 (2)°, V=1304.83 Å3, Z=4, Dm = 1.23, Dx =1.25 Mg m-3, μ(Mo Kα, λ=0.7107 Å)=0.232 mm-1, F(000)=520. The structure was solved by direct methods and refined to an R value of 0.042 using 1127 intensity measurements. The C=C and C-N bond distances differ considerably from their normal values. An appreciable rotation [38.3(4°] about the C=C bond is observed, the bond length being 1.414(5) Å. This is due to the combination of push-pull and steric effects.
