The title compound, C15H25N5, is an aminalization product between 2,6-diacetyl­pyridine and 1,3-diamino­propane. It crystallizes with two independent mol­ecules in the asymmetric unit with different conformations. In the first mol­ecule, the methyl groups are cis oriented with respect to the pyridine ring [N—C—C—C torsion angles = 72.5 (1) and 80.3 (1)°], while they are trans oriented in the second mol­ecule [N—C—C—C torsion angles = 82.6 (1) and -90.8 (1)°]. Each of the two mol­ecules forms centrosymmetric dimers held together by N—H[cdots, three dots, centered]N hydrogen bonds, thus forming R 2 2(16) rings. The two dimers are inter­linked by additional N—H[cdots, three dots, centered]N bonds into R 4 4(14) rings, building chains along the a axis. These patterns influence the orientation (either equatorial or axial) of the N—H bonds.
