ABSTRACT:
The invention relates to compounds of the metal dihydrocarbyl-dithiophosphyl-dithiophosphate type, their manufacture and use. These compounds can be represented by the general formula: ##STR1## wherein R is a monovalent substantially hydrocarbon-containing radical of 1 to 30 carbon atoms, X and Y are each a hydrogen atom or a monovalent substantially hydrocarbon-containing radical of 1 to 30 carbon atoms, M is a metal selected from zinc, cadmium, lead and antimony or an oxygen--and/or sulfur--containing molybdenum complex, and n is the valence of said metal M. The compounds according to the invention can be used as additives for lubricants wherein they act as a very efficient wear preventive.
