Magnetism in coordination complexes

The effects of the lanthanide contraction on lanthanide-induced shifts are estimated using simulated structures for a set of lanthanide chelates. The variations of the Ln-donor distances cause small conformational changes in the coordination polyhedron of the Ln(III) cation, and the induced pseudocontact shifts for a series of Ln complexes vary gradually going from La(III) to Lu(III). As a result of data manipulation these gradual variations may sometimes show up as an abrupt break in the middle of the lanthanide series.
