Abstract

The reaction of the nickel complexes [(dppm)NiBr₂] [dppm = 1,1-bis(diphenylphosphanyl)methane] and [(dppe)NiBr₂] [dppe = 1,2-bis(diphenylphosphanyl)ethane] with stanna-closo-dodecaborate [Bu ₃NH]₂[SnB₁₁H₁₁] (1) yielded the trigonal-bipyramidal coordination compounds [Bu₃NH] ₄-[(dppm)Ni(SnB₁₁H₁₁)₃] (2) and [Bu₃NH]₄[(dppe)Ni(SnB₁₁H₁₁) ₃] (3). The square-planar compound [Bu₃NH] ₂[(ImiPr₂Me₂)₂-Ni(SnB ₁₁H₁₁)₂] (4) (ImiPr₂Me₂ = 1,3-diisopropyl-4,5-di-methyl-imidazoliumylidene) could be obtained by the reaction of the N-heterocyclic carbene complex [(ImiPr₂Me ₂)₂-NiBr₂] with [Bu₃NH] ₂[SnB₁₁H₁₁] (1). The new coordination compounds were characterized by heteronuclear NMR spectroscopy and single-crystal X-ray structure analysis.
