Abstract

The X-ray crystal structure of the elusive isomer of Os₃(CO)₁₀(PPh₃)₂ in which the two phosphine ligands are cis and trans with respect to the phosphine-substituted Os-Os edge has been determined; the first direct confirmation for the existence of this isomer in Os₃(CO)₁₀(PR₃)₂ clusters. In contrast to the trans,trans isomer, the cis,trans isomer shows little twisting of the Os(CO)₃(PPh₃) groupings with respect to the Os(CO)₄ unit.
