2-Methyl-4,6-bis(1-methylhydrazino)pyrimidine

D. J. Hutchinson, L. R. Hanton and S. C. Moratti

Abstract: In the title compound, C₇H₁₄N₆, the amine groups of the two methylhydrazino substituents are orientated in the opposite direction to the methyl substituent at the 2-position of the pyrimidine ring. The molecule is almost planar with only the two amine N atoms lying substantially 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 molecule. Each molecule is linked to two others through N-HN hydrogen bonds between the two amino groups, forming a one-dimensional chain in the [010] direction. Offset face-to-face - stacking interactions between the pyrimidine rings organize these chains into a two-dimensional array [centroid-centroid distance = 3.789 (2) Å].
