The crystal structure of diphenyl (benzylcarbamothioyl)phosphoramide is reported. In the P(O)NHC(S)NH moiety the conformations are different from the conformations of similar moiety in analogous structures retrieved from the Cambridge Structural Database. The calculated energies of the most stable seven conformers of the title compound (gas phase) are compared with the conformer found in the crystal structure, and the latter shows a relatively high energy value. Energy framework calculations show the significant role of N-H...O hydrogen bonds in the c direction and the weak interactions with main ly dispersion component in the other two directions. The hydrogen bonds and weak interactions were confirmed by the quantum theory of atoms in molecules.
