Abstract

{The thermolysis of Os3(CO)11PPhFc2 affords Os3(CO)9[mu(3)-aryne][mu(3)-P(C5H4)Fe(C5H5)] (aryne = ferrocyne, (C5H3)Fe(C5H5) (2), benzyme, C6H4 (6)). Likewise the ferrodicyne Fe(C5H3)2 derivative Os3(H)2(CO)8-(PPr2iC5H2)Fe(C5H2PPr2i)Os3(H)2(CO)8 (3) is obtained from Os3(CO)11(PPr2iC5H4)Fe(C5H4PPr2i)Os3(CO)11. In 2 the ferrocyne moiety is a symmetrical four-electron donor to an open Os3P cluster; in 6 the benzyne is an unsymmetrical donor of two to four electrons to the open Os3P cluster. In 3 each aryne ring acts as an unsymmetrical four-electron donor to a closed Os3 cluster that is also coordinated to the PPr2i group of the other aryne ring.
