Further studies on dppm-stabilized mixed-metal clusters: X-ray structure of PdPtCoCl(CO)3(μ-dppm)2 1
Autor: Yves Dusausoy, Daniel Bayeul, Pierre Braunstein, Claude de Bellefon
Publikováno v: Journal of Cluster Science. 6:175-185
The metalloligated mixed-metal cluster [PdPtCo2(CO)7(μ-dppm)2] (2) (dppm = μ-Ph2PCH2PPh2) possesses numerous potential reaction centers (e.g., metal(s), metal-metal bonds, CO, and dppm ligands) and this has previously led to an investigation of the
