Bottom Line: The H atoms on these amine groups point inwards towards the aromatic ring, such that the lone pair of electrons points outwards from the mol-ecule.Each mol-ecule is linked to two others through N-H⋯N hydrogen bonds between the two amino groups, forming a one-dimensional chain in the [010] direction.Offset face-to-face π-π stacking inter-actions between the pyrimidine rings organize these chains into a two-dimensional array [centroid-centroid distance = 3.789 (2) Å].

ABSTRACT
In the title compound, C(7)H(14)N(6), the amine groups of the two methyl-hydrazino substituents are orientated in the opposite direction to the methyl substituent at the 2-position of the pyrimidine ring. The mol-ecule is almost planar with only the two amine N atoms lying substanti-ally out of the mean plane of the pyrimidine ring [by 0.1430 (2) and 0.3092 (2) Å]. The H atoms on these amine groups point inwards towards the aromatic ring, such that the lone pair of electrons points outwards from the mol-ecule. Each mol-ecule is linked to two others through N-H⋯N hydrogen bonds between the two amino groups, forming a one-dimensional chain in the [010] direction. Offset face-to-face π-π stacking inter-actions between the pyrimidine rings organize these chains into a two-dimensional array [centroid-centroid distance = 3.789 (2) Å].
