The metal oxide clusters [W3O9]− and [Mo3O9]− were studied by photoelectron spectroscopy and theoretical calculations, which show that [W3O9] and [Mo3O9] both have a D3h structure with a low-lying unoccupied molecular orbital formed from the metal d orbitals. Occupation of this orbital by one or two electrons leads to aromatic anions (see picture) with strong three-center, one-electron and three-center, two-electron metal–metal bonds, respectively.
