title: 1-Prop-2-ynyl-1H-benzimidazol-2-amine.
abstract: In the title compound, C(10)H(9)N(3), the benzimidazol-2-amine and CH(2)-C CH units are not coplanar, with a dihedral angle of 60.36° between their mean planes. The crystal structure is stabilized by inter-molecular N-H⋯N hydrogen bonding and π-π inter-actions [centroid-centroid distances 3.677 (1) and 3.580 (1) Å], assembling the mol-ecules into a supra-molecular structure with a three-dimensional network.
