Full title: Ferrocyne and ferrodicyne. Preparation and structures of Os3(CO)9[μ3-(C5H 3)Fe(C5H5)][μ3-P(C 5H4)Fe(C5H5)], Os3(H)2(CO)8(PPri2C 5H2)Fe(C5H2PPri 2)Os3(H)2(CO)8, and Os3(CO)9[μ3-C6H 4][μ3-P(C5H4)Fe(C 5H5)]. The thermolysis of Os3(CO)11PPhFc2 affords Os3(CO)9[μ3-aryne][μ3-P(C 5H4)Fe(C5H5)] (aryne = ferrocyne, (C6H3)Fe(C5H5) (2), benzyne, C6H4 (6)). Likewise the ferrodicyne Fe(C5H3)2 derivative Os3(H)2(CO)8-(PPri2C 5H2)Fe(C5H2PPri 2)Os3(H)2(CO)8 (3) is obtained from Os3(CO)11(PPri2C5H 4)Fe(C5H4PPri2)Os 3(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 PPri2 group of the other aryne ring.
