Beschreibung
Zusammenfassung:	A lubricating oil composition is provided comprising a major amount of an oi l of lubricating viscosity and a minor amount of, as an additive, at least one compound comprising a polynuclear molybdenum core and bonded thereto one or more anionic ligands capable of rendering the compound oil-soluble or oil-dispersible, wherein th e ratio of the number of molybdenum atoms in the core to the number of said ligands is 1:1, such as 3:2 or greater.
