Abstract:	μ-(Diselenium)bis(tricarbonyliron), (μ-Se₂)Fe₂(CO)₆, has been found to have reactivity typical of organic diselenides, RSeSeR. Reaction with two molar equivalents of LiBEt₃H converts (μ-Se₂)Fe₂(CO)₆ to the dianion, (μ-LiSe)₂Fe₂(CO)₆. Organolithium reagents, RLi, cleave its SeSe bond, giving (μ-LiSe)(μ-RSe)Fe₂(CO)₆. Low valent transition metal species, e.g., (Ph₃P)₂Pt, insert into the SeSe bond. (μ-Se₂)Fe₂(CO)₆ is fragmented by the action of dicobalt octacarbonyl, giving (μ₃-Se)FeCo₂(CO)₉.
