Abstract

Linked bis (β-diketiminato) rare-earth metal complexes based on the ethylene-bridged ligand [C2H4 (BDIDClP) 2] H2 [DClP= 2, 6-Cl2C6H3] and the cyclohexyl-bridged ligands [Cy (BDIAr) 2] H2 [Ar= PMP (= p-MeOC6H4), Mes (= 2, 4, 6-Me3C6H2), DIPP (= 2, 6- iPr2C6H3)] were prepared via amine elimination starting from [Ln {N (SiMe3) 2} 3](Ln= La, Y). The three cyclohexyl-bridged complexes [{(R, R)-Cy (BDIMes) 2} YN (SiMe3) 2]((R, R)- ...
