Abstract: There is provided an improved method for preparing compounds of the formula Mo.sub.4 S.sub.4 L.sub.6 comprising:heating a solution of a compound having the formula MoL.sub.4, wherein L is a 1,1-dithioacid ligand, at a temperature and for a time sufficient to form the Mo.sub.4 S.sub.4 L.sub.6 compound. Preferably, the MoL.sub.4 compound is dissolved in an organic solvent and the solution is heated at temperatures above 25.degree. C., up to the boiling point of the solvent and, more preferably, at temperatures in the range of from about 50.degree. C. to about 250.degree. C.

Abstract: The present invention is predicated on the discovery that Mo(III) containing compounds will react with salts of a 1,1-dithioacid to form Mo.sub.4 S.sub.4 L.sub.6. Accordingly, there is provided a method for preparing compounds of the formula Mo.sub.4 S.sub.4 L.sub.6 wherein L is a 1,1-dithioacid ligand comprising:contacting a Mo(III) containing compound with the salt of a 1,1-dithioacid at temperatures and for a time sufficient to form the Mo.sub.4 S.sub.4 L.sub.6 compound. Preferably, the Mo(III) containing compound is dissolved in an organic solvent and the solution is heated at temperatures above about 25.degree. C. up to the boiling point of the solvent and, preferably, at temperatures in the range of about 25.degree. C. to about 250.degree. C.

Abstract: In accordance with this invention, there is provided a lubricating composition comprising a major amount of an oil of lubricating viscosity and a minor amount of an additive having the formula Mo.sub.2 L.sub.4 wherein L is a ligand selected from xanthates and mixtures thereof and, in particular, xanthates having a sufficient number of carbon atoms to render the additive soluble in the oil. In general, the xanthate ligand, L, will have form about 2 to 30 carbon atoms.
