[b]Abstract: [/b]Reactions of the unsaturated mixed metal cluster complex PtOs3(CO)7(PBut3)(μ-PBut2)(μ4-CHCMeCH), [b]1[/b], with hydrogen, HGePh3, and PhC2H have been investigated. Compound [b]1[/b] reacts reversibly with hydrogen at room temperature to yield the dihydrido complex PtOs3(CO)7(PBut3)(μ-PBut2)(μ4-CHCMeCH)(μ-H)(H), [b]2[/b].A computational analysis shows that the hydrogen addition occurs byoxidative addition at the electronically unsaturated platinum atom andpasses through two unstable intermediates before giving the finalproduct [b]2[/b]. Compound [b]1[/b] reacts with HGePh3 at the Ge−H bond to form the complex PtOs3(CO)7(PBut3)(μ-PBut2)(μ4-CHCMeCH)(GePh3)(μ-H), [b]3[/b], but in this reaction the HGePh3 addition occurred at one of the osmium atoms and a CO ligand was shifted to the platinum atom. Compound [b]1[/b] reacts with PhC2H by loss of the platinum atom and the PBut3 ligand to give the compound Os3(CO)7(μ-PBut2)[μ3-η5-CHCMeC(H)CCPhH], [b]4[/b]. In the process, the PhC2H molecule became bonded to the CHCMeCH ligand in [b]1[/b]and its hydrogen atom was shifted to the phenyl-substituted carbon atomto form a triply bridging CHCMeC(H)CCPhH ligand. All of the productswere characterized by single-crystal X-ray diffraction analyses.

[b]Remards:[/b] 还是与Richard Adams组的合作，他们的实验发现不饱和金属团簇化合物1可以与H2、PhCCH以及PH3GeH反应生成新的化合物，其中在室温下与H2的反应是可逆的。我们则通过计算解释了它们的反应机理。按Richard Adams的习惯，作者以Last name排序。

呵呵，按last name 排序，那Adams岂不每次都是一作，似乎有些unfair.

第二作者是Boswell，还是有点亏的，呵呵。

Adams太不厚道了，还有什么last name比他的还前？
