The molecule of the title compound, C18H21N9, 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 Å), the distortion from a hexagonal 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.
