The crystal and molecular structure of (diisopropoxythiophosphoryl)(dipheny
lthiophosphoryl)- amine (i-PrO)(2)P(S)NHP(S)Ph-2 was studied by single crys
tal X-ray diffraction. The bond lengths, bond angles, and torsion angles we
re determined. The molecules in the crystal form centrosymmetric dimers by
a pair of intermolecular hydrogen bonds N-H . . .S=P.
