Abstract A better understanding of the chemical bond in general is gained from the electronic structure of the molecular complex [{RhBi 7 }Br 8 ]. The interactions in the central Bi 5 ring can be interpreted as an unusual five‐center, four‐electron bond based on ab initio calculations and group theory. Of the linear combinations of five Bi p orbitals two of the molecular orbitals are binding (depicted in the sketch).
