6-Amino-3-methyl-4-(4-nitro-phen-yl)-1-phenyl-pyrazolo[3,4-b]pyridine-5-carbonitrile.

ABSTRACT: The title compound, C(20)H(14)N(6)O(2), contains four rings. The dihedral angle between the pyridine ring and the pyrazole ring is 1.9?(1)°, i.e. almost coplanar, which gives rise to a conjugated structure. The dihedral angle between the nitro-substituted phenyl ring and the pyridine ring is 76.3?(1)° and that between the pyrazole ring and the non-substituted phenyl ring is 40.5?(1)°. In the crystal structure, symmetry-related mol-ecules are linked by N-H?O and C-H?N hydrogen bonds.
