Quinolin-3-amine [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the crystal structur of the achiral title compound, C(9)H(8)N(2), N-H⋯N hydrogen bonds connect the mol-ecules into zigzag chains in [100]. Weak inter-molecular N-H⋯π inter-actions further consolidate the crystal packing.
