The reaction of the nickel complexes [(dppm)NiBr 2 ] [dppm = 1,1‐bis(diphenylphosphanyl)methane] and [(dppe)NiBr 2 ] [dppe = 1,2‐bis(diphenylphosphanyl)ethane] with stanna‐ closo ‐dodecaborate [Bu 3 NH] 2 [SnB 11 H 11 ] ( 1 ) yielded the trigonal‐bipyramidal coordination compounds [Bu 3 NH] 4 [(dppm)Ni(SnB 11 H 11 ) 3 ] ( 2 ) and [Bu 3 NH] 4 [(dppe)Ni(SnB 11 H 11 ) 3 ]( 3 ). The square‐planar compound [Bu 3 NH] 2 [(Im i Pr 2 Me 2 ) 2 Ni(SnB 11 H 11 ) 2 ] ( 4 ) (Im i Pr 2 Me 2 = 1,3‐diisopropyl‐4,5‐dimethyl‐imidazoliumylidene) could be obtained by the reaction of the N‐heterocyclic carbene complex [(Im i Pr 2 Me 2 ) 2 NiBr 2 ] with [Bu 3 NH] 2 [SnB 11 H 11 ] ( 1 ). The new coordination compounds were characterized by heteronuclear NMR spectroscopy and single‐crystal X‐ray structure analysis.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
