1,2,3,5-Tetramethyl-1H-pyrazol-2-ium triiodide

The title salt, C7H13N2+·I3−, was obtained unintentionally by methylation of 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine and subsequent fragmentation. The pyrazolium ring is almost planar (r.m.s. deviation = 0.003 Å) and the triiodide anion deviates slightly from linearity [I—I—I = 177.099 (12)°]. No directional interactions occur in the crystal
