Abstract

The reaction between [NiCl₂(PPh₃)₂] and [Li{C(SiMe₃)₂(SiMe₂C₅H₄N-2)}] in tetrahydrofuran gave the monomeric Ni(I) compound [Ni{C(SiMe₃)₂(SiMe₂C₅H₄N-2)}(PPh₃)], which shows planar coordination at Ni with Ni-C 2.025(4) Å, together with the Ni(II) silanolato compound [Ni{C(Si-Me₃)(SiMe₂C₅H₄N-2)(SiMe₂O)}]₂ as a minor product, however, the corresponding reaction with [PdCl₂(PPh₃)₂] gave [Pd(μ-Cl){C(SiMe₃)₂(SiMe₂C₅H₄N-2)}]₂, which has a chloride-bridged structure with an unusual fold angle of 60°at the Cl···Cl axis.
