The first phosphorane 3, C30H27N3O12P4, Mr=745.43, bearing three P-P bonds, was synthesized and its crystal structure was determined by X-ray diffraction method. The crystal data are as follows: colorless crystals, orthorhombic, space group P212121, a=9.4387(1), b=18.424(2), c=19.358(2), V=3366.57(7)3, Dc=1.471Mg/m3, λ(MoKα)=0.71073, μ(MoKα)=0.291mm-1, F(000)=1536, Z=4. The structure was refined to R=0.0598 and wR(F2)=0.0758 for 5946 observed reflections [I>2σ(I)]. The geometry of the P(4) atom is pyramidal, whereas the coordination geometry around the P(1), P(2) and P(3) atoms is a strongly distorted trigonal-bipyramid.
