title: 2,3,5-Triphenyl-2H-tetra-zol-3-ium iodide.
abstract: The asymmetric unit of the title mol-ecular salt, C(19)H(15)N(4) (+)·I(-), contains four 2,3,5-triphenyl-2H-tetra-zol-3-ium cations and five iodide anions, with two of the latter lying on crystallographic inversion centres. In each cation, the tetra-zole ring is essentially planar (r.m.s. deviations = 0.004-0.007 Å). The dihedral angles between the tetra-zole ring and its three attached benzene rings in the four independent cations are: 12.9 (4), 67.0 (4), 48.1 (4); 20.8 (4), 51.1 (4), 62.3 (4); 11.4 (4), 52.3 (4), 47.3 (4) and 6.0 (4), 85.7 (4), 43.5 (4)°. A C-H⋯I hydrogen bond and C-H⋯π inter-actions are observed in the crystal.
