Abstract:

In the title compound, C16H18N6O, an N-carbonyl­imidazole derivative of pyrazoline-1-carboximid­amide, the -electron density of the N atom in the 1-position on the pyrazoline ring is delocalized through the amidine moiety and the adjacent carbonyl group. The imidazole ring, though coplanar with the rest of the mol­ecule, is deconjugated. The pyrazoline ring adopts a flat-envelope conformation, having the substituted phenyl ring oriented perpendicular to the mean plane of the heterocycle. Both of the two potential hydrogen-bond donors are involved in intramolecular hydrogen-bonding interactions.
