Synthesis and Structure of [(OC)₄Fe Si(O<i>t</i>Bu)₂·HMPT], a Donor‐Stabilized Silanediyl (“Silylene”) Complex

Abstract

The first stable silanediyl complex 1 is monomeric both in solution and in the crystalline state. 1 has a polar SiFe bond and is stabilized by adduct formation with hexamethylphosphoric triamide (HMPT). As expected, the silanediyl ligand occupies an apical position of the trigonal-bipyramidally coordinated iron atom.
