 Title    Iminoacetylacetonat-Komplexe der Lanthanoide: Synthese, Eigenschaften und Struktur Im inoacetylacetonate Complexes of Lanthanides: Synthesis, Properties and Structure  
 Abstract    The reactions of (^5-C5Me5)2Ln(J u-Cl)2ML2 (Ln = Y, La, Lu; M = Li, K; L = Et20 , dme) 3 a —c with the sodium iminoacetylacetonates 2 a -b yield monomeric metallocene chelate com­ plexes (?75-C5Me5)2Ln(OCM e=CHCM e=NR), (Ln = Y, La, Lu; R = C6H5, C6H4-4-Me) 4 a -d which have been characterized by IR, NM R and mass spectrometry. In the case of the lan­ thanum complex 4c, the chelating structure was confirmed by an X-ray structure analysis. 4c crystallizes monoclinically in space group P2,/c with a = 10.232(3), b = 10.216(1), c = 29.047(7)Ä, a = y = 90.0°, ß = 97.76(3)°, Z = 4, and R = RK = 0.0378 for 4026 observed reflections. The new complexes are sensitive to oxygen and moisture and soluble in all com­ mon organic solvents.
