(E)-3,5-Dimethyl-1-p-tolyl-4-(p-tolyldiazenyl)-1H-pyrazole
There are two independent molecules, A and B, in the asymmetric unit of the title compound, C(19)H(20)N(4), in each of which the N=N double bond has an E conformation. The dihedral angles between the pyrazole ring and the p-tolyl rings in the 1- and 4-positions are 22.54 (8) and 35.73 (7)°, respect...

| description | There are two independent molecules, A and B, in the asymmetric unit of the title compound, C(19)H(20)N(4), in each of which the N=N double bond has an E conformation. The dihedral angles between the pyrazole ring and the p-tolyl rings in the 1- and 4-positions are 22.54 (8) and 35.73 (7)°, respectively, in molecule A. The corresponding dihedral angles in molecule B are 28.13 (8) and 22.18 (8)°. In the crystal, the A and B molecules are linked by weak C—H⋯π interactions, leading to inversion dimers in each case. |
