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

ABSTRACT: 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-nitro-phenyl 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 inter-actions 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].
