title: P,P-Diphenyl-N-(1,1,2,2-tetra-phenyl-1λ-diphosphanyl-idene)phosphinous amide.
abstract: The title compound, C(36)H(30)NP(3), a structural isomer of tris-(diphenyl-phosphino)amine, was unexpectedly isolated as the sole phospho-rus-containing product from the reaction of Mg[N(PPh(2))(2)](2)(THF)(2) (THF is tetra-hydro-furan) with CO(2). Its identity was confirmed by (31)P 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.
