Amitraz.

In the asymmetric unit of the title compound {systematic name: N'-(2,4-di-methyl-phen-yl)-N-[N-(2,4-di-methyl-phen-yl)carbox-imido-yl]-N-methyl-methanimidamide}, C19H23N3, which is a formamidine pesticide, there are two independent and conformationally similar mol-ecules, with the dihedral angle between the mean planes of the 2,4-di-methylbenzene rings in each mol-ecule being 41.63 (6) and 42.09 (5)°. The crystal structure is stabilized by a C-H⋯N hydrogen bond, as well as weak inter-molecular C-H⋯π and π-π inter-actions [ring centroid separation = 3.7409 (15) Å], giving one-dimensional chains extending down the b direction.
