摘要
The title azo compound, C16H16N4, was synthesized from 2,6-dimethylaniline. The diazenyl group adopts a trans (E) conformation, with an N=N bond length A of 1.265 (4) angstrom. The pyrazole ring is approximately planar. In the crystal, zigzag chains along the b-axis direction with a C(3) is graph-set motif are formed by N-H center dot center dot center dot N hydrogen bonds involving the pyrazole moiety.
