N‐Substituted Amido Derivatives of Lanthanides
1980
The synthesis of lanthanide amido complexes of the type Ln(CH3CONR)3 (I), (OPri)Ln(C6H5CONC6H5)2 (II), and (OBut)Ln(C6H5CONC6H5)2 (III) [where Ln = La, Pr, Nd; R = C6H5, p-NO2C6H4, p-BrC6H4] are described. Infrared spectra indicate deprotonation of the secondary amide (anilide). Anion coordination is proposed as chelating bidenate ligands.
N-Substituierte Amido-Derivate von Lanthanoiden
Beschreibung der Darstellung von Amidokomplexen des Typs Ln(CH3CONR)3 (I), (OPri)Ln(C6H5CONC6H5)2 (II), und (OBut)Ln(C6H5CONC6H5)2 (III) [Ln = La, Pr, Nd; R = C6H5, p-NO2C6H4, p-BrC6H4]. Aus IR-Spektren ergibt sich eine Deprotonisierung des sekundaren Amids (Anilids). Die Anionen wirken wahrscheinlich chelatartig als zweizahnige Liganden.
