Abstract
The synthesis, molecular and electronic structures of covalently linked dinuclear units having MM quadruple bonds (M = Mo or W) are described together with their attendant spectroscopies. Particular attention is paid to compounds where M2δ to bridge π bonding generates strongly coupled M2 centers whose mixed valence ions formed upon one electron oxidation traverse the Class II/III border.
