Abstract

The trigonal-planar versus pyramidal geometries of tris (ring) divalent lanthanide title complexes (Ln= Sm, Eu, Yb) have been studied using crystallographic and density functional theory analysis. Both the analyses and exchange reactions between these complexes and (C5Me5) 2Ln support highly ionic bonding with a low activation barrier of the bending mode that can be easily perturbed by crystal packing.
