    摘要: A lubricating oil composition comprising, or made by mixing, a major amount of an oil of lubricating viscosity and a minor amount of at least one compound comprising a polynuclear molybdenum core having bonded thereto one or more monoanionic ligands capable of rendering the compound oil-soluble or oil-dispersible, and further comprising at least one ionic species that is not required to confer oil-solubility or oil-dispersibility to the compound, wherein the combination of said one or more monoanionic ligands and said at least one ionic species confers electrical neutrality to the compound and wherein the ratio of the number of molybdenum atoms in the core to the number of said ligands is greater than 1:1.

    摘要: The invention relates to a composition that is the reaction of a fullerene containing at least one corrannulene ring structure and Y.sub.2 X.sub.2, wherein Y is Se or S, and X is Cl or Br. Generally, these compounds may be represented by the formula C.sup.f.sub.n X.sub.6 Y.sub.2 or more particularly C.sup.f.sub.n X.sub.5 (YYX). In the formula C.sup.f.sub.n more specifically, is a fullerene having at least one corrannulene ring structure. The compositions may be made by reacting fullerenes with Se.sub.2 X.sub.2 or S.sub.2 X.sub.2 wherein X is Cl or Br, preferably in liquid form and preferably heated for a time sufficient to produce the novel compositions. The compositions may be isolated in crystalline form by precipitation with a solvent such as hexane. In crystalline form the compositions may be represented by the generic formula C.sup.f.sub.n X.sub.8 Y.sub.4, or more particularly, C.sup.f.sub.n X.sub.5 (YYX).mY.sub.2 X.sub.2 because in crystalline form the compositions are typically associated with .mY.sub.2 X.sub.2 molecules wherein m is an integer at least equal to 1. The compositions have utility as crosslinking agents and lubricating oil and polymer additives, particularly as vulcanizing agents.

    摘要: Briefly stated, the present invention encompasses a new class of rhenium 1,1-dithioacid complexes and their method of preparation. The complexes have the general formula [L.sub.2 Re(.mu.-S)].sub.2 wherein L is a dithioacid or similar ligand, and .mu. denotes the fact that the sulfur atoms in the core of the complex bridge the two rhenium atoms in the complex. Thus, the core structure for such typical compounds is generally of the form: ##STR1## where the dangling valences are associated with the sulfur atoms of a 1,1-dithioacid, L.
