At room temperature, Fe2(CO)6(μ-Se2) reacts with Ru3(CO)12 to form Fe2Ru3(CO)17(μ₄-Se)(μ₃-Se), and with Ru(CO)4(C2H4) to form Fe2Ru(CO)9(μ₃-Se)2. The latter reacts with Fe(CO)5 under visible light irradiation to give Fe3Ru(CO)11(μ₄-Se)2, and with Ru(CO)4(C2H4) to form Fe2Ru2(CO)11(μ₄-Se)2. Visible light irradiation of a solution containing Fe3(CO)9(μ₃-Se)2 and Fe(CO)5 yields Fe4(CO)11(μ₄-Se)2. A solution containing Fe3(CO)9(μ₃-Se)2 and Ru(CO)4(C2H4) at room temperature with stirring yielded Fe3Ru(CO)11(μ₄-Se)2.
