1-[3-({[Bis(2-methyl-prop-yl)carbamo-thio-yl]amino}-carbon-yl)benzoyl]-3,3-bis-(2-methyl-prop-yl)thio-urea.

The title compound, C26H42N4O2S2, adopts a shallow U-shape as both pendant arms of the 1,3-substituted benzene ring are orientated in the same direction. The thione S atoms lie to the same side of the benzene ring and the carbonyl O atoms to the other. The most prominent feature of the crystal packing is the formation of inversion dimers mediated by N-H⋯S hydrogen bonds. One of the 2-methyl-propyl groups is statistically disordered over two positions.
