Abstract

Reduction of an N-heterocyclic carbene (NHC) adduct of SnCl2, viz. [(IPr)SnCl2] (IPr = :C{N(Dip)C(H)}2; Dip = 2,6-diisopropylphenyl), with a magnesium(I) dimer, has afforded the first NHC complex of a row 5 element in its diatomic form, [(IPr)Sn[double bond, length as m-dash]Sn(IPr)]; a computational analysis of the complex indicates that it comprises a singlet state, doubly bonded tin(0) fragment, :Sn[double bond, length as m-dash]Sn:, datively bonded by two NHC ligands.
