6-Amino-3-methyl-4-(3-nitro­phen­yl)-1-phenyl-1H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile

The title compound, C(20)H(15)N(5)O(3), was synthesized by the one-pot reaction of a four-component reaction protocol in aqueous medium. The pyrano[2,3-c]pyrazole system is essentially planar, with a maximum deviation of 0.026 (2) Å. The 3-nitro­phenyl and phenyl rings make dihedral angles of 81.11 ...

Sumario:The title compound, C(20)H(15)N(5)O(3), was synthesized by the one-pot reaction of a four-component reaction protocol in aqueous medium. The pyrano[2,3-c]pyrazole system is essentially planar, with a maximum deviation of 0.026 (2) Å. The 3-nitro­phenyl and phenyl rings make dihedral angles of 81.11 (5) and 13.36 (1)°, respectively, with the mean plane of the pyrano[2,3-c]pyrazole ring. The crystal structure is stabilized by N—H⋯N hydrogen bonds, which form infinite chain propagating along the c axis and by N—H⋯O hydrogen bonds, which form infinite chains propagating along the a axis. There are also N—O⋯N—C dipole–dipole inter­actions along the a axis with an O⋯N distance of 3.061 (3) Å, which is shorter than that of the N—H⋯O hydrogen bond [3.196 (3) Å].
