Synthesis of a series of cationic coinage metal (Au: 2 – 4 , Ag: 5 , and Cu: 6 ) complexes of asymmetric diborenes ( 1 a , 1 b ) is reported. X‐ray diffraction analysis reveals that the metal center interacts unsymmetrically with the B 2 moiety and the terminal boron atom exhibits pronounced pyramidal geometry. A computational study shows that in complexes 2 – 6 , the bonding between the B 2 units and the metal center is dominated by electrostatic interactions concomitant with non‐negligible covalent contributions.
