Abstract

Treatment of [Os₃(CO)₁₀(NCMe)₂] with platinum bis(alkynyl) complexes cis-[Pt(C≡CPh)₂(L)] [L = 4,4′-dimethyl-2,2′-bipyridine (Me₂bipy), 4,4′-bis(tert-butyl)-2,2′-bipyridine (tBu₂-bipy)] at room temperature readily affords the novel, spiked-triangular heterometallic cluster complexes [Os₃Pt(CO)₉(μ₄-η ²-C≡CPh)(η¹-C≡CPh)(L)] (L = Me₂bipy 1, tBu₂bipy 2) in moderate yields. X-ray analysis of both complexes reveals that one alkynyl moiety is coordinated to the metal atoms in a μ₄-η²(II) mode, accompanied by a concomitant transfer of an η¹-C≡CPh group from the platinum centre to the osmium atom to give a metal framework with an osmium atom apically bonded to an Os₂Pt triangle.
