PURPOSE: Provided is a process for the separation and recovery of an unsaturated hydrocarbon from its mixture with at least one other material by the selective and reversible complexation of the unsaturated hydrocarbon using a single cubane-type cluster of palladium, molybdenum and sulfur as a complexation agent. CONSTITUTION: A process comprises (a) contacting the feed gas and an acidic aqueous liquid solution of a single cubane-type cluster of the formula £(H2O)9Mo3S4PdX|X3 wherein X is a halide ion, and at least 2 molar in a hydrohalic acid as a complexation agent, under conditions such that the complexation agent has a substantially greater affinity to form, and does selectively form, at least one water-soluble complex with the at least one other component, such that a substantial portion of the at least one unsaturated hydrocarbon thereby dissolves in the aqueous solution; (b) separating the resulting aqueous solution from the feed gas; (c) contacting the aqueous solution from step(b) with a gas phase under conditions such that the at least one complex dissociates in the aqueous solution and the resulting at least one dissociated unsaturated hydrocarbon is stripped from the aqueous solution into the gas phase; and (d) separating the resulting gas phase from the aqueous solution.
