The coordination of carbohydrate to metal ions is important
because
it may be involved in many biochemical processes. The synthesis and
characterization of several novel lanthanide-erythritol complexes
(TbCl3·1.5C4H10O4·H2O (TbE(I)), Pr(NO3)3·C4H10O4·2H2O (PrEN), Ce(NO3)3·C4H10O4·2H2O (CeEN), Y(NO3)3·C4H10O4·C2H5OH (YEN), Gd(NO3)3·C4H10O4·C2H5OH (GdEN)) and
Tb(NO3)3·C4H10O4·C2H5OH (TbEN) are reported. The
structures of these complexes in the solid state have been determined
by X-ray diffraction. Erythritol is used as two bidentate ligands
or as three hydroxyl group donor in these complexes. FTIR spectra
indicate that two kinds of structures, with water and without water
involved in the coordination sphere, were observed for lanthanide
nitrate-erythritol complexes. FIR and THz spectra show the formation
of metal ion-erythritol complexes. Luminescence spectra of Tb-erythritol
complexes have the characteristics of the Tb ion.
