PCT No. PCT/US88/00609 Sec. 371 Date Oct. 26, 1988 Sec. 102(e) Date Oct. 26, 1988 PCT Filed Feb. 26, 1988 PCT Pub. No. WO88/06489 PCT Pub. Date Sep. 7, 1988.The present invention discloses two polyoxoanion supported metal complexes found to be useful in olefin hydrogenation. The complexes are novel compositions of matter which are soluble in organic solvents. In particular, the compositions of matter comprise Ax[LnIr(I)xX2M15 M'3O62]x- and Ay[LnIr(I)xX2M9M'3O40]y- where L is a ligand preferably chosen from 1,5-cyclooctadiene (COD), ethylene, cyclooctene, norbornadiene and other olefinic ligands; n=1 or 2 depending upon the number of double bonds present in the ligand L; X is a "hetero" atom chosen from B, Si, Ge, P, As, Se, Te, I, Co, Mn and Cu; M is either W or Mo; M' is preferably Nb or V but Ti, Zr, Ta, Hf are also useful; and A is a countercation preferably selected from tetrabutyl ammonium and alkali metal ions.
