The neutral six-coordinate silicon(IV) complexes 2 and 3 (mixture of cis-3 and trans-3) were synthesized by reaction of the donor-stabilized silylene bis[N,N'-diisopropylbenzamidinato(-)]silicon(II) (1) with SO2 . Compounds 2 and 3 are the first silicon(IV) complexes with chelating sulfito or dithionito ligands, and 3 is even the first molecular compound with a chelating dithionito ligand. Compounds 2 and 3 were structurally characterized by crystal structure analyses and multinuclear NMR spectroscopic studies in the solid state and in solution.
中性六配位硅(IV)配合物2和3(顺式-3和反式-3的混合物)通过供体稳定的硅烯双[N,N'-二异丙基苯脒基(-)]硅(II)(1)与SO₂反应合成。化合物2和3是首批含有螯合亚硫酸根或连二亚硫酸根配体的硅(IV)配合物,而3甚至是首个含有螯合连二亚硫酸根配体的分子化合物。通过晶体结构分析以及固态和溶液中的多核NMR光谱研究对化合物2和3进行了结构表征。
