Building bridges : The combination of the Lewis acidic dichloroboryl complex [(η 5 ‐C 5 Me 5 )Fe(CO) 2 BCl 2 ] and a Lewis basic [Pd(PR 3 )] fragment gives the first dinuclear monoboryl complex with a symmetric μ, η 2 bridging BR 2 ligand (see structure). The dative nature of the palladium–boron bonding interaction makes the dinuclear compound a rare example of a transition‐metal borane complex.
