title: 3,3'-Dibenzoyl-1,1'-(butane-1,4-diyl)-dithio-urea.
abstract: In the centrosymmetric title compound, C(20)H(22)N(4)O(2)S(2), the carbonyl group forms an intra-molecular hydrogen bond with the NH group attached to the butanediyl linker, resulting in a six-membered ring. There are also inter-molecular C-H⋯S inter-actions in the crystal structure, and π-π inter-actions between phenyl groups [2.425 (3) Å].
