Reactions of (Et2N)2P-P(SiMe3)Li with [Cp2MCl2] (M= Zr, Hf) in toluene or pentane yield the related terminal phosphanylphosphido complexes [Cp2M(Cl){η1-(Me3Si)P-P(NEt2)2}]. The solid statestructure of [Cp2Hf(Cl){η1-(Me3Si)P-P(NEt2)2}] was established by single crystal X-ray diffraction. The reaction of (Et2N)2P-P(SiMe3)Li with [Cp2ZrCl2] in THF or DME solutions leads to the formationof deep red crystals of the first neutral diamagnetic zirconocene-phosphanylphosphinidene dimer [Cp2Zr{m2-P-P(NEt2)2}2ZrCp2]. The molecular structure of this compound was confirmed by X-raydiffraction. The reactions of (R2N)2P-P(SiMe3)Li with [CpZrCl3] yield the related tetraphosphetanes R2NP(μ2-PSiMe3)2PNR2, which apparently are formed as a result of a transfer of NR2 groups from a Patom to the Zr atom.
