1,3-Bis(2-methylprop-2-enoyl)-1H-benzimidazol-2(3H)-one

N. Haridharan and V. Ramkumar

Abstract: The molecules of the title compound, C15H14N2O3, possesses crystallographically imposed twofold rotational symmetry, so the asymmetric unit contains one half-molecule. The fused-ring system deviates significantly from planarity; the planes of the five- and six-membered rings are twisted with respect to each other by 3.0 (1)°. In the crystal, weak C-H...O hydrogen bonds link molecules related by translation in [010] into chains.
