Abstract

The reaction between [NiCl2(PPh3)2] and [[upper bond 1 start]Li{C(SiMe3)2(SiMe2C5 H4N[upper bond 1 end]-2)}] in tetrahydrofuran gave the monomeric Ni(I) compound [[upper bond 1 start]Ni{C(SiMe3)2(SiMe2C5H 4N[upper bond 1 end]-2)}(PPh3)], which shows planar coordination at Ni with Ni–C 2.025(4) Å, together with the Ni(II) silanolato compound [[upper bond 1 start][upper bond 2 start]Ni{C(Si- Me3)(SiMe2C5H4 N[upper bond 2 end]-2)(SiMe2O[upper bond 1 end])}]2 as a minor product, however, the corresponding reaction with [PdCl2(PPh3)2] gave [[upper bond 1 start]Pd(μ-Cl){C(SiMe3)2(SiMe 2C5H4N[upper bond 1 end]-2)}]2, which has a chloride-bridged structure with an unusual fold angle of 60° at the Cl···Cl axis.
