Synthesis and Reactivity of an Iron-Tin Complex with Adjacent Stannylidyne and Ferriostannylene Units.

ABSTRACT: Heavier transition metal carbyne analogs hold significant potential for cooperative activation of small molecules. However, complexes containing more than one heavier tetrylidyne ligand RE (E = Si, Ge, Sn, Pb) are rare due to the high oligomerization tendency of RE ligands. In this study, we describe the complex [Fe(SnAr')₂] (1; Ar' = 2,6-Dipp₂-C₆H₃, Dipp = 2,6-ⁱPr₂-C₆H₃), which features adjacent Fe-Sn single and double bonds. Complex 1 exhibits versatile reactivity with transition metal and main group compounds. Treatment of complex 1 with Ni(COD)₂ (COD = 1,5-cyclooctadiene) yields the tetranuclear complex [Fe(μ-SnAr')₂Ni] (2), characterized by a
