Treatment of Ru3 (CO) 12 or Os3 (CO) 12 with sodium in ether solvents at various reaction temperatures provides efficient preparations of several large anionic carbonyl clusters of ruthenium and osmium. The combinationof Ru3 (CO) 12 and 1 equiv of sodium (Ru3: Na= 1: 1) affords Ru6 (CO) 182" in refluxing tetrahydrofuran (66 C) but Ru6C (CO) 162" inrefluxing diglyme (162 C). Under the latter conditionsRu6 (CO) 182" is converted quantitatively to Ru6C (CO) 162~. Treatmentof Os3 (CO) 12 with sodium (Os3: Na= 1: 1) indiglyme at 162 C yields Os6 (CO) 182". Pyrolysis of Os6 (CO) 182" in triglyme (216 C) gives Os10C (CO) 242" as the major product. The decanuclear compound also is formed from the direct reaction of Os3 (CO) 12 with sodium (Os3: Na= 1.66: 1 or 1: 1) in tetraglyme at 230-260 C. Oxidation of Ru€ C (CO) 162" and Os6 (CO) 182" with aqueous ferric chloride in a carbon monoxide atmosphere produces Ru6C (CO) 17 and Os6 (CO) 18 in good yields. A compound formulated as Os6C (CO) 17 is isolated in low yield from the similar oxidation of reaction mixturesproduced upon pyrolysis of Os6 (CO) 182". This is suggested as evidence for the formation of Os6C (CO) 162" under the conditions for conversion of Os6 (CO) 182" to Os10C (CO) 242".
