(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, C19H20N4, 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
