substituent morpholine) accompanied by different [C (O) NH] P (O)[N] 2 (phosphoric
triamide, 1) and [N] P (O)[O] 2 (amidophosphoric acid ester, 2) skeletons are investigated by
single crystal X-ray diffraction and completed by FT-IR and 1 H, 13 C, 31 P NMR
spectroscopy. Structures 1 and 2 crystallize in the triclinic space group P 1¯ and the
monoclinic space group I2/a, respectively, both with one independent molecule in the …
