Zusammenfassung:A complex characterised in that it is a beta -diketonate complex of Ce with 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octane-dione (hfod), which corresponds to the following formula: Ce(fod)4 is disclosed. A complex characterised in that it is a beta -diketonate complex of Ce and M with 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octane-dione (hfod) which corresponds to the following formula M[Ce(fod)4] wherein M represents Na, Li, K, Cs and Rb is also disclosed. The volatile and thermally stable complex of cerium, Ce(fod)4, and the alkali metal-cerium beta -diketonate intermediates useful in its preparation are sources of mixed metals, such as Na[Ce(fod)4]. The present invention provides advantages over the prior art.
