Charge changes everything : The cationic terminal aminoborylene complex [CpFe(CO) 2 (BNCy 2 )] + [BAr F 4 ] − ( 1 , Cy= cyclohexyl, Ar F =3,5‐(CF 3 ) 2 C 6 H 3 ; Fe orange, B green, N blue, O red, C gray) was structurally characterized. DFT studies (see HOMO−2) indicate delocalized π bonding along the linear Fe‐B‐N framework and significant FeB and BN multiple‐bond character.
