Abstract
A surprisingly easy access to the preparation of transition‐metal clusters is the reaction of MCl2 (M Co, Ni) with PhP(SiMe3)2 and PPh3. In this way [Co4(μ3‐PPh)4(PPh3)4] and [Ni8(X)4(μ4‐PPh)6(PPh3)4] (XCl and CO) can be isolated. The paramagnetic complex with X Cl contains 116 valence electrons and can be considered as a mixed‐valence cluster of Ni0 and Ni1+.Keywords
