First examples of 3d-uranium compounds derived from single-compartment Schiff base ligands: Syntheses, crystal structures and d-d band correlation

This paper deals with the syntheses, characterization, crystal structures and UV-Vis spectroscopy of three diphenoxo-bridged CuII(UVIO2) compounds derived from single-compartment Schiff base ligands. Interestingly, these three compounds are first examples of 3d-5f systems derived from single-compartment ligands. An excellent correlation of d-d band position with the displacement of CuII from basal plane has been observed.
