A second polymorph of 2,4,6-tris-(3,5-dimethyl-1H-pyrazol-1-yl)-1,3,5-triazine.

The mol-ecule of the title compound, C(18)H(21)N(9), is nearly planar, with the three pyrazole rings aligned at 2.40†(5), 9.27†(5) and 9.71†(5)° with respect to the triazine ring. The triazine ring is planar (r.m.s. deviation = 0.005†à ), the distortion from a hexa-gonal arrangement arising from the angles at the N [112.4†(1)-113.1†(1)°] and C [127.1†(1)-127.6†(1)°] atoms deviating from 120°. The crystal studied was an inversion twin.
