title: 3,3'-Diphenyl-1,1'-(butane-1,4-di-yl)dithio-urea.
abstract: The asymmetric unit of the title compound, C(18)H(22)N(4)S(2), contains one half-mol-ecule, the complete mol-ecule being generated by crystallographic inversion symmetry. The crystal structure features two inter-molecular N-H⋯S hydrogen-bonding inter-actions, the first generating an infinite chain along the b axis and the second an infinite chain along the a axis, together forming an inter-locking structure.
