Reaction of OsO4 with CO at 125 °C and 75 atm was found to result in a stable compound A with the empirical formula OsC4O4. Compound A was found to contain 3 metal-metal bonds. Reaction of A with excess of sodium metal followed by treatment with H3PO4 was found to result in compound B with the molecular formula OsH2C4O4. Heating of B was found to result in the release of a colourless gas and formation of a compound C with empirical formula OsHC4O4. C on treatment with MeI was found to get converted to D with release of a hydrocarbon gas. D on further treatment with Na/Hg followed by MeI gave E with the empirical formula OsC5H3O4. Compounds A-E obey 18 electron rule and no bridging ligands were also observed. Suggest structures for compounds A-E.
