An ortho­rhom­bic polymorph of 3,4-di­amino­benzo­nitrile

The title compound, C(7)H(7)N(3), is an ortho­rhom­bic polymorph that crystallizes in the space group Pca2(1). The previously reported monoclinic form [Geiger & Parsons (2013 ▶) Acta Cryst. E69, o452] crystallizes in the space group P2(1)/c (Z = 4). In the crystal, two independent HN—H⋯N C hydro...

description The title compound, C(7)H(7)N(3), is an ortho­rhom­bic polymorph that crystallizes in the space group Pca2(1). The previously reported monoclinic form [Geiger & Parsons (2013 ▶) Acta Cryst. E69, o452] crystallizes in the space group P2(1)/c (Z = 4). In the crystal, two independent HN—H⋯N C hydrogen bonds link the mol­ecules into chains along the a-glide plane. Two further independent HN—H⋯NH(2) hydrogen bonds join the chains, forming a three-dimensional network.
