Ethyl N-[(benz­yloxy)thio­carbon­yl]carbamate

In the title compound, C₁₁H₁₃NO₃S, the dihedral angle between the benzyl and carbamate groups is 12.67 (10)°. The S atom and the carbonyl O atom are positioned anti to each other. In the crystal, pairs of N—H...S hydrogen bonds link mol­ecules into inversion dimers.

1-Benzoyl-2-thio­biuret

In the title compound [systematic name: N-(carbamoyl­carb­a­mo­thio­yl)benzamide], C₉H₉N₃O₂S, the benzoyl and terminal urea fragments adopt cisoid and transoid conformations, respectively, with respect to the S atom. The benzoyl and thio­biuret groups are almost coplanar, making a dihedral angle of 8.48 (5)°. The mol­ecular structure is stabilized by an intra­molecular N—H...O hydrogen bond. In the crystal, N—H...O and N—H...S hydrogen bonds link the mol­ecules into a sheet parallel to the bc plane.

N-(5-Eth­oxy-1,3,4-thia­diazol-2-yl)benzamide

In the title compound, C₁₁H₁₁N₃O₂S, the dihedral angle between the thia­diazole and phenyl rings is 28.08 (7)°. In the crystal, mol­ecules are linked into an inversion dimer by a pair of inter­molecular N—H...N hydrogen bonds with an R₂²(8) graph-set motif.
