Abstract

The title mol-ecule, C13H16N6, crystallizes from hexane as a mol-ecular crystal with no strong inter-molecular inter-actions (the shortest C-H⋯N contact is longer than 3.38 Å). A relatively short intra-molecular contact (3.09 Å) has a C-H⋯N angle of 118° which is quite small to be still considered a hydrogen bond. The three pyrazole rings form a propeller-like motif, with one methylpyrazole unit almost perpendicular to the mean plane of the three rings [82.20 (6)°]. The other two methylpyrazole units, with nitrogen donor atoms oriented in opposite directions, are oriented at 67.26 (6) and 72.53 (6)° to the mean plane.

Keywords: 1,1′,1′′-methane­triyltris(3-methyl-1H-pyrazole); crystal structure; tripyrazolyl­methane.
