Abstract

[LSi(η²-P₄)] (L = CH[C(Me)N(Dipp)][C(CH₂)N(Dipp)], Dipp = 2,6-diisopropylphenyl) forms well-defined 1 : 1 and 2 : 1 complexes with N-heterocyclic carbene nickel fragments. The cluster compound [(IDipp)Ni₂P₈(SiL)₂] (IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) is selectively formed by thermolysis of the complex [(IDipp)Ni(μ-η^2:2-P₄)SiL].
