  摘要：

  Reactions between LiC(SiMe3)(2)(SiMe2C5H4N-2), 1, and the halides GeCl2.dioxane, SnCl2, and PbCl2 gave the isostructural compounds MCl{C(SiMe3)(2)(SiMe2C5H4N-2)} (M = Ge, 2; Sn, 3; or Pb, 4) which contain three-coordinate M. Treatment of the tin derivative 3 with MeI gave the oxidative addition product SnMeClI{C(SiMe3)(2)(SiMe2C5H4N-2)}, 51 and this reacted with AgOCOCF3 or AgOSO2C6H4Me-4 to give, respectively, the compounds SnMeX2{C(SiMe3)(2)(SiMe2C5H4N-2)} with X = OCOCF3, 6, or OSO2C6H4Me-4, 7. Despite the presence of the bulky C(SiMe3)(2)(SiMe3C5H4N-2) ligand, the Sn atom in the solid state structures of 6 and 7 is five-coordinate, and multinuclear NMR studies show that five-coordinate species are present also in THF solutions of 5, 6, and 7.

  The reaction between [NiCl2(PPh3)2] and [LiC(SiMe3)2(SiMe2C5 H4N-2)}] in tetrahydrofuran gave the monomeric Ni(I) compound [NiC(SiMe3)2(SiMe2C5H 4N-2)}(PPh3)], which shows planar coordination at Ni with Ni–C 2.025(4) Å, together with the Ni(II) silanolato compound [NiC(Si- Me3)(SiMe2C5H4 N-2)(SiMe2O)}]2 as a minor product, however, the corresponding reaction with [PdCl2(PPh3)2] gave [Pd(μ-Cl)C(SiMe3)2(SiMe 2C5H4N-2)}]2, which has a chloride-bridged structure with an unusual fold angle of 60° at the Cl···Cl axis.

  之间的反应 [NiCl2(PPh3)2] 和 [LiC(SiMe3)2(SiMe2C5) H4N-2)}]在四氢呋喃中得到单体 镍(I)化合物 [NiC(SiMe3)2(SiMe2C5H) 4N-2)}(PPh3)]，显示平面配位 在 Ni 处，Ni ≤ C 2.025(4) ≤，以及 Ni(II) 硅烷醇化合物 [NiC(Si- Me3)(SiMe2C5H4) N-2)(SiMe2O)}]2 作为次要产品， 然而，相应的反应 [PdCl2(PPh3)2]给出 [Pd(μ-Cl)C(SiMe3)2(SiMe 2C5 -2)}]2，其具有 氯桥结构，其折叠角不寻常，为 60° Cl····Cl轴。
