The title azo compound, CHN, was synthesized from 2,6-di-methyl-aniline. The diazenyl group adopts a () conformation, with an N=N bond length of 1.265 (4) Å. The pyrazole ring is approximately planar. In the crystal, zigzag chains along the -axis direction with a (3) is graph-set motif are formed by N-H⋯N hydrogen bonds involving the pyrazole moiety.
标题偶氮化合物CHN由2,6-二甲基苯胺合成。重氮基采取()构象,N=N键长为1.265(4)Å。吡唑环近似平面。在晶体中,沿轴方向具有(3)图集模式的锯齿链由涉及吡唑部分的N-H⋯N氢键形成。
