An unprecedented,reversible coordination mode rearrangement:eta~3(B-H) vs.eta~1(Sn) stanna-closo-dodecaborate coordination

摘要

The synthesis of the ruthenium stanna-closo-dodecaborate complex [Bu_3MeN]_2[Ru(dppb)(MeCN)_2(SnB_11H_11)_2] by an unprecedented,reversible eta~3(B-H) to eta~1(Sn) rearrangement of [Bu_3MeN]_2[Ru(dppb)(SnB_(11)H_(11))_2] is described and the product is characterized by multinuclear NMR spectroscopy and single-crystal X-ray diffraction.
