Abstract
The present invention relates to a compound of the Formula I:and a lubricating composition containing and a method for preparing the same. In Formula I, R1-R5 and R6-R10 are independently selected from the group consisting of hydrogen, hydrocarbyl groups and hydrocarbyl groups containing heteroatoms, such that the total carbon atoms from Q1 and Q2 is from 6 to 166 carbon atoms, and molybdate anion (Y) is a binuclear sulfur-containing dianion selected from the group consisting of [Mo2S8O2]2−, [Mo2S9O]2−, and [Mo2S10]2.
