Abstract

Measurements of the equilibrium constants for ligand exchange (MeCN, 295 K) involving the axial donor in a C₄- symmetric, mono-capped, square antiprismatic cationic Eu complex, supported by calculations based on an electrostatic perturbation model, have been interpreted in terms of a predominant ligand polarisation interaction defined by observation of the hypersensitive ΔJ = 2 normalised emission intensity, in association with measurements correlating ΔJ = 1 band splitting and ¹H NMR dipolar shifts that vindicate Bleaney’s theory of magnetic anisotropy.
