Abstract: The non-H atoms in the structure of the title molecule, C7H7N3, are almost coplanar (r.m.s. deviation = 0.018 Å). The two amine groups each donate two and accept one weak N-HN hydrogen bonds. N-HN hydrogen bonding between the amine and nitrile groups results in chains parallel to  in the crystal structure. The chains are cross-linked by N-HN hydrogen bonds between amine groups, giving rise to an infinite three-dimensional network.
