(E)-3-Dimethylamino-1-(1,3-thiazol-2-yl)prop-2-en-1-one

X.-Y. You, Y.-J. Shi and L.-T. Yu

Abstract: In the title compound, C8H10N2OS, the 3-(dimethylamino)prop-2-en-1-one unit is approximately planar [give r.m.s. deviation] and the mean plane through the seven non-H atoms makes a dihedral angle of 8.88 (3)° with the thiazole ring. The carbonyl and ring C=N double bonds adjacent to the carbonyl group are trans [N-C-C-O = 172.31 (15) °], while the conformation of the carbonyl and propene double bonds is cis [O-C-C-C = 2.2 (2)°]. In the crystal, short C-H...N and C-H...O interactions together with C-H...[pi] interactions generate a three-dimensional network.
