Reactions of (Et(2)N)(2)P-P(SiMe(3))Li with [Cp(2)MCl(2)] (M = Zr, Hf) in toluene or pentane yield the related terminal phosphanylphosphido complexes [Cp(2)M(Cl){η(1)-(Me(3)Si)P-P(NEt(2))(2)}]. The solid state structure of [Cp(2)Hf(Cl){η(1)-(Me(3)Si)P-P(NEt(2))(2)}] was established by single crystal X-ray diffraction. The reaction of (Et(2)N)(2)P-P(SiMe(3))Li with [Cp(2)ZrCl(2)] in THF or DME solutions leads to the formation of deep red crystals of the first neutral diamagnetic zirconocene-phosphanylphosphinidene dimer [Cp(2)Zr{μ(2)-P-P(NEt(2))(2)}(2)ZrCp(2)]. The molecular structure of this compound was confirmed by X-ray diffraction. The reactions of (R(2)N)(2)P-P(SiMe(3))Li with [CpZrCl(3)] yield the related tetraphosphetanes R(2)NP(μ(2)-PSiMe(3))(2)PNR(2), which apparently are formed as a result of a transfer of NR(2) groups from a P atom to the Zr atom.
（Et(2)N)(2)P-P(SiMe(3))Li 与 [Cp(2)MCl(2)]（M = Zr，Hf）在甲苯或戊烷中的反应生成相关的末端膦基膦化物配合物 [Cp(2)M(Cl){η(1)-(Me(3)Si)P-P(NEt(2))(2)}]。[Cp(2)Hf(Cl){η(1)-(Me(3)Si)P-P(NEt(2))(2)}]的固体结构通过单晶 X 射线衍射确定。（Et(2)N)(2)P-P(SiMe(3))Li 与 [Cp(2)ZrCl(2)]在 THF 或 DME 溶液中的反应导致第一中性顺磁二茂锆-膦基膦化物二聚体 [Cp(2)Zr{μ(2)-P-P(NEt(2))(2)}(2)ZrCp(2)]的深红色晶体的形成。该化合物的分子结构通过 X 射线衍射得到证实。（R(2)N)(2)P-P(SiMe(3))Li 与 [CpZrCl(3)]的反应生成相关的四磷杂环戊烷 R(2)NP(μ(2)-PSiMe(3))(2)PNR(2)，显然是由于 NR(2)基团从 P 原子转移到 Zr 原子而形成的。
