The title compound, C36H30NP3, a structural isomer of tris(diphenylphosphino)amine, was unexpectedly isolated as the sole phosphorus-containing product from the reaction of Mg[N(PPh2)2]2(THF)2 (THF is tetrahydrofuran) with CO2. Its identity was confirmed by 31P NMR spectroscopy and single-crystal X-ray diffraction. The geometry at the two P(III) atoms is trigonal pyramidal, while the P(V) atom adopts a distorted tetrahedral geometry.
