Abstract:	The spiked triangular triosmium-platinum cluster complex Os₃Pt(μ-H)(μ₄-η²-CCPh)(CO)₁₀(PCy₃) has been synthesised by treatment of the unsaturated Os₃Pt(μ-H)₂(CO)₁₀(PCy₃) with LiCCPh followed by protonation. Crystallographic analysis reveals an unusual twisted configuration of the μ₄-η²-CCPh ligand about the triosmium framework such that the complex may be regarded as a platina-allenyl moiety coordinated to an Os₃(μ-H)(CO)₉ unit.
