Abstract

Reactions of the clusters Os₃(μ-H)₂(μ ₃-1-OC₁₀H₆)(CO)₉, 1, and Os ₃(μ-H)(μ-2-OC₁₀H₇)(CO)₁₀, 2, with the group 15 ligands EPh₃ (E=P, As, Sb) generally afforded the mono- and, or disubstituted derivatives. These derivatives tend to decompose during chromatographic separations on silica gel; thus one of the decomposition products from the reaction of 1 with PPh₃ has been identified as Os(H)₂(CO)₂(PPh₃)₂, 3. The molecular structures of 3, as well as the derivatives Os₃(μ-H) ₂(μ₃-1-OC₁₀H₆)(CO) ₈(AsPh₃), 4, Os₃(μ-H)₂(μ ₃-1-OC₁₀H₆)(CO)₇(SbPh ₃)₂, 5c, Os₃(μ-H)(μ-2-OC ₁₀H₇)(CO)₈(AsPh₃)₂, 7b, and Os₃(μ-H)(μ-2-OC₁₀H₇)(CO) ₈(SbPh₃)₂, 7c, have been determined by single crystal X-ray diffraction studies.
