Reduction of an N-heterocyclic carbene (NHC) adduct of SnCl(2), viz. [(IPr)SnCl(2)] (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=Sn(IPr)]; a computational analysis of the complex indicates that it comprises a singlet state, doubly bonded tin(0) fragment, :Sn=Sn:, datively bonded by two NHC ligands.
锡(II)的 N-杂环卡宾（NHC）加合物，即 [(IPr)SnCl2]（IPr = :C{N(Dip)C(H)}(2)；Dip = 2,6-二异丙基苯基）与镁（I）二聚体反应，得到了首例处于双原子形式的第 5 族元素的 NHC 配合物，[(IPr)Sn=Sn(IPr)]；该配合物的计算分析表明，它包含一个单重态、二价锡（0）片段，:Sn=Sn:，由两个 NHC 配体以配位键结合。
