title: 4,5-Diamino-benzene-1,2-dicarbonitrile.
abstract: The mol-ecular skeleton of the title mol-ecule, C(8)H(6)N(4), is essentially planar [maximum deviation from the mean plane of 0.037 (2) Å]. All N atoms are involved in the formation of inter-molecular N-H⋯N hydrogen bonds. The crystal packing exhibits also dipole-dipole inter-actions between the cyano groups of neighbouring mol-ecules [C⋯C 3.473 (2) Å].
