1-Benzoyl-4-thio­biuret

In the title compound (systematic name: {[(phenyl­formamido)­carbon­yl]amino}­methane­thio­amide), C(9)H(9)N(3)O(2)S, both benzoyl and terminal thio­urea fragments adopt transoid conformations with respect to the central carbonyl O atom. The benzoyl and thio­biuret groups are almost coplanar, making a dihedral angle of 4.40 (8)°. The mol­ecular structure is stabilized by two intra­molecular N—H⋯O hydrogen bonds. In the crystal, N—H⋯O and N—H⋯S hydrogen bonds link the mol­ecules into a tape running along [101].
