Compositions of the formula: MoSvow(RR'N)x(CSy)z are dispersants, anti-oxidants and friction-reducing agents for lubricant compositions. In the formula v is from 0.5 to 3, w is a number such that v+w is from 0.5 to 3, x is from 0.8 to 5, y is from 1 to 3, and z is from 0.5 to 5, R is an alkenylsuccinyl di- or polyamine group having 15 to 300 carbon atoms, and R' is hydrogen, an alkyl group of 1 to 20 carbon atoms, an alkenylsuccinyl amine or an alkenylsuccinyl polyamine group which can be the same as, or different from R. The composition can be prepared by reacting CS2 with a composition of the formula: MoSaObHc(RR'N)x wherein x R and R' have the meanings given above a=0.5 to 3; b=2.5 to 0; and c=0 to 3, x=0.8 to 5; using a molar change ratio of CS2 to molybdenum of 0.5:1 to 5:1.
