5-Nitro-1-(prop-2-yn-1-yl)-2,3-dihydro-1H-1,3-benzodiazol-2-one

Abstract

In the two independent mol­ecules of the title compound, C10H7N3O3, the nitro substitutent is twisted slightly with respect to the benzodiazol fused-ring system [dihedral angles = 4.9 (3) and 8.5 (1)°]. The two independent mol­ecules are disposed about a pseudo inversion center and are held together by N—H⋯O hydrogen bonds. The supramolecular dimer is essentially planar [dihedral angle between the fused rings = 2.0 (1)°]. Adjacent dimers are linked by acetyl­ene–nitro C—H⋯O inter­actions, generating a ribbon motif along (110).
