Abstract: The title compound, C19H25N5, adopts pseudo-C2 symmetry in which the non-substituted N atoms of the pyrazole rings are on opposite sides of the pyridine plane. The packing involves C-H, -, C-HN and hydrophobic CH3CH3 interactions, which are responsible for the observed columnar arrangement.
