  Condensation of [Mn2(CO)8(μ-PPh2)]− with Pd(II) assisted by Ag(I) leads to cluster disproportionation, viz. Mn2Pd2Ag(μ-Cl)(μ-PPh2)2(μ-dppm)(CO)8 and MnPd(μ-PPh2)(CO)4(η2-P–P) (P–P = dppm, dppe, dppf). The former shows a distorted bow-tie structure with two heterometallic triangles AgPdMn} sharing an Ag center. The unexpected phosphide migration across different metals holds the key to the cleavage and formation of metal–metal bonds. The bimetallic complexes are stabilized by all common diphosphines whereas the polymetallic structure is isolated only when supported by dppm. The latter shows three different types of heterometal–metal bonds Ag–Mn (2.6938(4) Å), Ag–Pd (2.7637(1) Å) and Mn–Pd (2.8183(9) Å) (average values).

  在 Ag(I) 的协助下，[Mn2(CO)8(δ-PPh2)]â 与 Pd(II) 的缩合导致了簇的歧化，即 Mn2Pd2Ag(δ-Cl)(δ-PPh2)2(δ-dppm)(CO)8 和 MnPd(δ-PPh2)(CO)4(δ-2-PâP) （PâP = dppm、dppe、dppf）。前者显示出扭曲的领结结构，两个异金属三角形AgPdMn}共享一个银中心。意想不到的磷化物在不同金属间的迁移是金属与金属键裂解和形成的关键。双金属复合物能被所有常见的二膦稳定，而多金属结构只有在得到二ppm支持时才会被分离。后者显示出三种不同类型的异金属-金属键：AgâMn（2.6938(4) Ã）、AgâPd（2.7637(1) Ã）和MnâPd（2.8183(9) Ã）（平均值）。

  Redox condensation of PPN[Mn-2(mu-PPh2)(CO)(8)] and PdCl2(eta(2)-dppm) gives bimetallic PdMn(mu-PPh2)(mu-dppm)(CO)(3)(PPh3) (1) with an unexpected formation of PPh3. The latter can be displaced when 1 reacts with free diphosphines (dppm, dppe, dppf) giving PdMn(mu-PPh2)(mu-dppm)(CO)(3)(Ph2P-X-P(=O)Ph-2) (2, X-CH2 (2a), C2H4 (2b), C5H4FeC5H4 (2c)) and [PdMn(CO)(3)(mu-PPh2)(mu-dppm)](2)(mu-Ph2P-X-PPh2) (3a). Complexes 2 are "A-frame"-type bimetallic complexes with an syn-dppm bridging the Mn-Pd bond. In contrast, complex 3a is a "double A-frarne" anti-bridged by dppm. As a result, the latter is trans to the Mn-Pd bonds. Both types of dppm bridges are substitutionally inert. Either bridging role is best served by dppm (and not dppe or dppf). The structures of the complexes were derived from NMR analyses of all complexes and X-ray single-crystal diffraction analyses of 1, 2a and 2b. The common and stable "A-frame"-type core in these bimetallics provides a thermodynamic driving force for the opposite transmetallation migration of phosphide and phosphine (dppm) when 1 is formed.
