The new ligand 1 ⊖ makes possible C ⃛H ⃛Co interactions in a complex. The complex, the title compound [Co(1) 2 ], was isolated from aqueous solution. The trick leading to pseudooctahedral coordination in [Co(1) 2 ] is the incorporation of boron into the [3.3.1] bicyclic framework. Co is coordinated by two N (equatorial) and one H (apical) from each of the two ligands. The H is bonded to C‐2 of the ring system.
