Abstract

Triple-decker complexes with a bridging diborolyl ligand CpCo(μ-1,3-C₃B₂Me₅)-M(C₅R₅) (M = Fe, R = H (2a), Me (2b); M = Ni, R = H (3)) were synthesized in high yields by electrophilic stacking of the sandwich anion [CpCo(1,3-C₃B₂Me₅)]⁻ with the labile complexes [CpFe(SMe₂)₃]⁺, [Cp*Fe(MeCN)₃]⁺, and [CpNi(SMe₂)₂]⁺, respectively. The structures of complexes 2a, 2b, and 3 were determined by X-ray diffraction. The influence of additional unpaired electrons on the structural changes due to the transition from the 30-electron FeCo triple-decker complexes to the 32-electron NiCo complex was investigated.

带桥接二硼基配体的三层配合物：合成与结构

具有桥接二硼基配体的三层配合物CpCo(μ-1,3- c3b2me5)-M(C5R5) (M = Fe, R = H (2a), Me (2b))；M = Ni, R = H(3))是由夹心阴离子[CpCo(1,3- c3b2me5)]−与不稳定的配合物[CpFe(SMe2)3]+、[Cp*Fe(MeCN)3]+和[CpNi(SMe2)2]+亲电叠加而成的。配合物2a、2b和3的结构通过x射线衍射测定。研究了30电子FeCo三层配合物向32电子NiCo配合物转变过程中，附加的未配对电子对结构变化的影响。
