Abstract: The asymmetric unit of the title compound, C15H15N3, contains two crystallographically independent molecules with very similar geometries. The imidazole and indenyl planes are approximately orthogonal, making dihedral angles of 88.21 (9) and 83.08 (9)%deg; in the two independent molecules. In the crystal, the imidazole units are linked by N-HN hydrogen bonds into chains parallel to the 101) plane stretched in the diagonal direction [translation vector (,1,0); C(4) motif]. Within a chain, there are two types of symmetrically non-equivalent alternating H-bonds which slightly differ in their parameters.
