Carbonylcyanometalates as building blocks: heterometallic complexes containing Mn(μ-CN)M (M = Cu, Au, Ni, Pd or Pt), Mn(μ-CN)Pd(μ-dppm)2Mn and Mn(μ-CN)M(μ-dppm)2Pd(μ-NC)Mn (M = Pt or Pd) chains of atoms and crystal structure of the mixed-metal cluster [Ru3{(μ3-NC)MnCp(CO)2}(μ-AuPPh3)(CO)10]†
Abstract
A comparison between the products obtained by reaction of the isosteric metalates [MoCp(CO)3]− (Cp = η5-C5H5) and [MnCp(or Cp′)(CN)(CO)2]− (Cp′ = η5-C5H4Me) with various mono- or poly-nuclear complexes of Cu, Au, Ni, Pd, Pt or Ru showed that the metal-centered basicity of the former leads to metal–metal bonding whereas the dominant σ-donor properties of the CN
