A process for addition curing organosilicone compositions using as catalysts rhodium- or iridium-nitrogen complex compounds having the formulae: (a) monometallic complexes, (L)MX(Y)2, and (b) bimetallic complexex, (L) [RhX(CO)2]2, wherein: M is a rhodium or iridium metal atom, L is a single or fused heterocyclic ligand comprising at least one five- or six-membered ring, said ligand having 2 to 4 ring nitrogen atoms in the same ring, Y is an uncharged ligand that fills one or two coordination positions of the metal atom, and X is Cl, Br, I, or CN. Preparation of the novel catalysts is disclosed. The cured compositions are useful as molded articles, such as gaskets, O-rings, and tubing.
