Syntheses and structures of the first terminal phosphanylphosphido complex of hafnium [Cp2Hf(Cl){η1-(Me3Si)P- P(NEt2)2}] and the first zirconocene- phosphanylphosphinidene dimer [Cp2Zr{μ2-P-P(NEt 2)2}2ZrCp2]

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 state structure of [Cp2Hf(Cl){η1-(Me 3Si)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 formation of deep red crystals of the first neutral diamagnetic zirconocene-phosphanylphosphinidene dimer [Cp2Zr{μ 2-P-P(NEt2)2}2ZrCp2]. The molecular structure of this compound was confirmed by X-ray diffraction. The reactions of (R2N)2P-P(SiMe3)Li with [CpZrCl3] yield the related tetraphosphetanes R2NP(μ 2-PSiMe3)2PNR2, which apparently are formed as a result of a transfer of NR2 groups from a P atom to the Zr atom.
