Activation of SO 2 by the donor‐stabilized bis(guanidinato)silylene [ i PrNC(N i Pr 2 )N i Pr] 2 Si ( 7 ) leads to the six‐coordinate sulfitosilicon(IV) complex 12 (obtained by treatment of 7 with 1.5 molar equivalents of SO 2 in n ‐hexane) or the six‐coordinate dithionitosilicon(IV) complex 13 (a co‐crystallizate of cis ‐ 13 and trans ‐ 13 ; obtained by treatment of 7 with a vast excess of liquid SO 2 ). Compounds 12 and 13 were characterized by elemental analyses, crystal structure analyses, and multinuclear NMR spectroscopic studies in the solid state and in solution. The six‐coordinate silicon(IV) complexes 12 , cis ‐ 13 , and trans ‐ 13 represent very rare examples of main‐group element compounds with an O , O ‐chelating sulfito or dithionito ligand.
