An uncommon interaction characterizes the Ni I –Ni I zwitterionic complex presented here. The μ‐Ph moiety of the tetraphenylborate ligand coordinates synfacially to the two Ni centers (see picture) and provides two pairs of electrons through an η 2 (C2,C3):η 2 (C5,C6) interaction that is strengthened as a result of the electrostatic attractions between the anion and the formally cationic Ni 2 fragment.
