Figure 1
A view of the dimer of (I), connected via pairs of intermolecular N—H⋯O=C hydrogen bonds (dashed lines), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. Dashed arrows indicate C—H⋯O=C hydrogen bonds to neighbouring molecules.
