Balance between van der Waals and coordination bond energies—Unified Model of coordination bond length in lanthanide complexes

This paper presents the variation of coordination bond lengths in lanthanide complexes as a balance between van der Waals and coordination bond energies. Each coordination atom moves in a unified potential well that is a combination of the Morse potential of its coordination bond and the van der Waals potentials of its neighboring coordination atoms. This is termed the Unified Model of coordinatio…
