(E)-N-{[6-chloro-4-(4-chlorophenyl)-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]pyridin-5-yl]methylene}benzene-1,2-diamine: a three-dimensional framework structure built from only two hydrogen bonds.

The molecules of the title compound, C(26)H(19)Cl(2)N(5), are conformationally chiral, with none of the aryl groups coplanar with the pyrazolo[3,4-b]pyridine core of the molecule. A single unique N-H...N hydrogen bond links the molecules into two symmetry-related sets of C(11) chains running parallel to the [011] and [011] directions, respectively, and these two sets of chains are linked into a continuous three-dimensional framework structure by a single unique C-H...N hydrogen bond which forms a chain parallel to the [100] direction.
