Abstract:
The title compound, C23H32N2OS, is a thio-urea-based insecticide. The dihedral angle between the phenyl ring and the diisopropyl benzene ring plane is 73.18 (6)°, while that between the plane of the thio-urea group and the diisopropyl benzene ring is 86.00 (5)°. Disorder was modelled for the S atom and the two methyl C atoms of the isopropyl group over two sets of sites with an occupancy ratio of 0.742 (4):0.258 (4). In the crystal, N-H⋯S hydrogen bonds link adjacent mol-ecules, forming R 2 (2)(8) inversion dimers that pack into chains along the b-axis direction.
