Abstract
The synthesis and characterization of divalent lanthanide complexes of a triazacyclononane-functionalized tetramethylcyclopentadienyl ligand are described. Addition of LnI 2 (THF) 2 (Ln = Sm, Yb; THF = tetrahydrofuran) to [C 5 Me 4 SiMe 2 ( i Pr 2 -tacn)]K (tacn = 1,4-diisopropyl-1,4,7-triazacyclononane) in THF yields the monomeric organolanthanides [C 5 Me 4 SiMe 2 ( i Pr 2 -tacn)]SmI (1) and [C 5 Me 4 SiMe 2 ( i Pr 2 -tacn)]YbI (2). The crystal structures of 1 and 2 have been determined.
