The reactions of cis-dihydridotetracarbonylosmium, H2Os(CO)4 with both Fe2(CO)9 and Co2(CO)8 have been studied at room temparature.With Fe2(CO)9, the major product is Fe2Os(CO)12 and H2FeOs3(CO)13 was obtained as a minor product.With Co2(CO)8, Co2Os(CO)11 and H2Co2Os2(CO)12 are obtained, along with an unstable compound which was identified mass spectrometrically as HOsCo(CO)8.Os(CO)5 reacts under UV irradiation with Co2(CO)8 to give Co2Os(CO)11.The main product of the reaction of H2Os2(CO)8 with Fe2(CO)9 is FeOs2(CO)12.
