On the Formation of a Fe 2 (CO) 6 Complex with a (Boryloxy)allyl Bridge The amino(imino)borane Me 3 Si( t Bu)NBN t Bu ( 1 ) reacts with (benzylideneacetone)tricarbonyliron ( 2 ) in 1:2 molar ratio to give a 50% yield of the hexacarbonyldiiron complex 3 with a fly‐over (boryloxy)allyl bridge, which crystallizes in the space group P 2 1 /c. The structure of 3 can be described as a pyramid with Fe(CO) 3 at the apex and a non‐planar pentagon [‐Fe(CO) 3 ‐O(BXX′)‐C(Me)‐CH‐C(Ph)‐] [X = NH t Bu, X′ = N(SiMe 3 ) t Bu] as the basis, but there is no bond between the apex and the O atom.
