Oil-soluble or oil-dispersible trinuclear molybdenum-sulfur compounds are made by reacting less than three, such as 1.5 to 2.5, preferably 2 to 2.1, molar equivalents of a disulfide with one molar equivalent of a compound containing the [Mo3S13]2-ion. The trinuclear compounds include S-containing ligands that are derived from the disulfide reactant via cleavage of the disulfide bond; the ligands are bound to the core via the S atoms. |
