ABSTRACT:
Oil-soluble or oil-dispersible trinuclear molybdenum-sulfur compounds are made by reacting less than three, such as 1.5 to 2.5, preferably two to 2.1, molar equivalents of a disulfide with one molar equivalent of a compound containing the [Mo.sub.3 S.sub.13 ].sup.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.
