A base-free synthetic route to anti-bimetallic lanthanide pentalene complexes

摘要

We report the synthesis and structural characterisation of three homobimetallic complexes featuring divalent lanthanide metals (Ln = Yb, Eu and Sm) bridged by the silylated pentalene ligand [ 1,4-{(SiPr3)-Pr-1}(2)C8H4](2-) (= Pn(+)). Magnetic measurements and cyclic voltammetry have been used to investigate the extent of intermetallic communication in these systems, in the context of molecular models for organolanthanide based conducting materials.
