3,4-Diaminobenzonitrile

D. K. Geiger and D. E. Parsons

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-H...N hydrogen bonds. N-H...N hydrogen bonding between the amine and nitrile groups results in chains parallel to [101] in the crystal structure. The chains are cross-linked by N-H...N hydrogen bonds between amine groups, giving rise to an infinite three-dimensional network.
