Abstract

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)}₂(μ₂-η²:η ²-C₆H₈-1,3)] and [{Os₄(CO) ₈(RCCR)(η⁶-C₆H₆)} ₂(μ₂-η²:η²-C ₆H₈-1,4)], respectively. The molecular structure of [{Os₄(CO)₈(MeCCMe)(η⁶-C₆H ₆)}₂(μ₂-η²:η ²-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 ₂-η₂:η²-bridge.
