The reactions of the osmium-tin cluster complexes Os3(CO) 12(μ3-SnPh)Ph, 9, and Os4(CO) 16(μ4-Sn), 10, with Pt(PBut 3)2 have been investigated. Two products, PtOs 3(CO)12(Ph)(PBut3)(μ3- SnPh), 11, and Pt2Os3(CO)12(μ2- Ph)(PBut3)2(μ3-SnPh), 12, were obtained from the reaction of 9 with Pt(PBut3) 2. These are mono- and bis-Pt(PBut3) adducts of 9 formed by the addition of a Pt(PBut3) group to the Os-Os bond in 11 and the Os-Os bond and Os-C bond to the σ-bonded phenyl group in 12. A PBut3 derivative of 11, Os 2(CO)8(μ3-SnPh)Os(CO)3(PBu t3)Ph, 13, was obtained by treating 12 with PBu t3. The reaction of 10 with Pt(PBut 3)2 provided the bis-Pt(PBut3) adduct Os4(CO)16[Pt(PBut3)] 2(μ4-Sn), 14, that was formed by the addition of a Pt(PBut3) group across the Os-Os bond of both Os2(CO) 8 groups in 10. All four new compounds 11-14 were characterized by single-crystal X-ray diffraction analysis.
