摘要：

The diselenide PhSeSePh reacts with [Os3(CO)10(MeCN)2] to give isomers of [Os3(CO)10(mu-SePh)2] which convert thermally to a compound of apparent formula [Os3(CO)9(SePh)2], which was shown by X-ray diffraction to be the triple oxidative addition product [Os3(mu-Ph)(mu-PhCO) (mu-3-Se)2(CO)8] in which the diselenide has cleaved into four separate ligand fragments as all three osmium(0) atoms are oxidised to osmium(II) atoms by an overall six-electron oxidation.
