NITROGEN CONTAINING METAL HYDROXIDE COMPLEXES

摘要

A process for making a substantially halide-free amine-metal hydroxide complex, comprising partitioning an aqueous solution of the hydrogen chloride or sodium chloride salt of one or more metal halides, in the presence of a base, with an organic solvent system containing an amine, wherein the metal of the metal halide is selected from the group consisting of gold, silver, copper, nickel, platinum and palladium. The complexes obtainable by such a process are also disclosed.
