1-Prop-2-ynyl-1H-benzimidazol-2-amine

Abstract

In the title compound, C10H9N3, the benzimidazol-2-amine and CH2—C[triple-bond]CH units are not coplanar, with a dihedral angle of 60.36° between their mean planes. The crystal structure is stabilized by intermolecular N—H...N hydrogen bonding and π–π interactions [centroid–centroid distances 3.677 (1) and 3.580 (1) Å], assembling the molecules into a supramolecular structure with a three-dimensional network.
