Abstract
Two new diphosphazane ligands, PriN(PPh2)(PO2C6H4) (1) and PriN{P(O2C6H4)}2 (3), have been synthesized and characterized by spectroscopic data. The structure of 1 has been confirmed by single crystal X‐ray diffraction. Crystal data: Monoclinic, C2/c, Z = 16, a = 34.149(5) Å, b = 9.717(6) Å, c = 29.439(5) Å, β = 125.11(2)°, V = 7991 Å3, R = 0.058, Rw = 0.061. This compound shows two different P–N bond lengths (1.654 (4) and 1.743(4) Å) and a P–N–P angle of 120.7(2)°. Variable temperature 31P NMR measurements for 1 and 3 throw light on the nature of the conformers present in solution.
