Full TextAbstract
A new acetyl phosphorylamidate P(O)[NHC( O)C6H4(4-NO2)][N(CH(CH3)2)(CH2C6H5)]2 has been synthesized and characterized by elemental analysis, 1H, 13C and 31P NMR, IR and single crystal X-ray diffraction. Single crystal X-ray analysis shows that it belongs to triclinic system, space group P 1, with a = 10.5868(16) A ° , b = 11.8058(18) A ° , c = 12.4364(19) A ° , a = 65.410(3) , b = 67.492(4) , c = 85.879(3) , V = 1,298.6(3) A ° 3, and Z = 2. The intermolecular PO HN hydrogen bond makes H-bonded dimer of molecule with Ci symmetry. In the crystal network, the dimers are aggregated in the chain arrays through p-stacking between p-NO2–C6H4–C(O)– NH– moieties. Moreover, weak C–H O and C–H p interactions exist in the crystal network.
