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

Abstract

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 = 0.005Å), 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.
