Chemical Structure Determination of Lantanides’ Coordination Compounds on the Basis of Their Absorption Spectra
Heretofore the majority of investigators considered the chemical bond in coordination compounds of the rare earths elements to be of ionic nature. Within the last years, however, many arguments have been submitted in favour of a partial covalency of the formed bonds. One of the reasons points out at the impossibility to deduce thermodynamical characteristics of the complexes on the mere basis of the ions charges and radii. An ample information on the geometry and chemical structure of the rare earth coordination compounds may be obtained on the basis of their absorption spectra.
