title: 4-(1H-Tetra-zol-5-yl)-1H-indole.
abstract: There are two mol-ecules with similar configurations in the asymmetric unit of the title compound, C(9)H(7)N(5), which are linked by inter-molecular N-H⋯N hydrogen bonds into chains with graph-set motif C(2) (2)(8) along the b axis. The indole core has the expected planar geometry in the two mol-ecules, with a maximum deviation of 0.008 (8) Å from the least-squares plane defined by the nine constituent atoms, and the dihedral angles between the indole and tetra-zole rings are similar [42.4 (2) and 42.7 (2)°].
