The reaction of [Os4(CO)9(RCCR)(η 6-C6H6)] (R = Me, Ph) with Me3NO in the presence of 1,3-cyclohexadiene or 1,4-cyclohexadiene yields the clusters [{Os4(CO)8(RCCR)(η6-C6H 6)}2222-C6H8-1,3)] and [{Os4(CO) 8(RCCR)(η6-C6H6)} 2222-C 6H8-1,4)], respectively. The molecular structure of [{Os4(CO)8(MeCCMe)(η6-C6H 6)}2222-C6H8-1,3)] has been determined by single crystal X-ray diffraction, and represents the first example of two osmium cluster fragments linked by 1,3-cyclohexadiene through a μ 222-bridge.
