The reactions of the osmium-tin cluster complexes Os3(CO)12(mu3-SnPh)Ph, 9, and Os4(CO)16(mu4-Sn), 10, with Pt(PBut3)2 have been investigated. Two products, PtOs3(CO)12(Ph)(PBut3)(mu3-SnPh), 11, and Pt2Os3(CO)12(mu2-Ph)(PBut3)2(mu3-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 sigma-bonded phenyl group in 12. A PBut3 derivative of 11, Os2(CO)8(mu3-SnPh)Os(CO)3(PBut3)Ph, 13, was obtained by treating 12 with PBut3. The reaction of 10 with Pt(PBut3)2 provided the bis-Pt(PBut3) adduct Os4(CO)16[Pt(PBut3)]2(mu4-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.
已对锇 - 锡簇合物Os3(CO)12(μ3 - SnPh)Ph（9）和Os4(CO)16(μ4 - Sn)（10）与Pt(PBut3)2的反应进行了研究。由9与Pt(PBut3)2反应得到了两种产物，即PtOs3(CO)12(Ph)(PBut3)(μ3 - SnPh)（11）和Pt2Os3(CO)12(μ2 - Ph)(PBut3)2(μ3 - SnPh)（12）。这些是9的单 - 和双 - Pt(PBut3)加合物，分别通过在11中将一个Pt(PBut3)基团加到Os - Os键上，以及在12中将一个Pt(PBut3)基团加到Os - Os键和Os - C键与σ键合的苯基上形成。通过用PBut3处理12得到了11的一个PBut3衍生物Os2(CO)8(μ3 - SnPh)Os(CO)3(PBut3)Ph（13）。10与Pt(PBut3)2的反应提供了双 - Pt(PBut3)加合物Os4(CO)16[Pt(PBut3)]2(μ4 - Sn)（14），它是通过在10中两个Os2(CO)8基团的Os - Os键上添加一个Pt(PBut3)基团形成的。所有四种新化合物11 - 14均通过单晶X射线衍射分析进行了表征。
