Tin–osmium cluster formation with a monomeric tin(II) alkyl: the formation, crystal structure and reactivity of [Os3(µ-H)SnR(CO)10], a formal stannyne complex of the osmium triangle {R = C(SiMe3)2C5H4N-2}

Abstract

The monomeric tin(II) species SnR₂{R = C(SiMe₃)₂C₅H₄N-2} reacts with [Os₃(H)₂(CO)₁₀] in hexane to give [Os₃(µ-H)SnR(CO)₁₀]1 quantitatively; 1 is the first formal stannyne complex of the triosmium nucleus, in which the picoline nitrogen is coordinated to the tin atom, and which is itself also reactive, being a potential precursor to high nuclearity SnOs clusters.
