New solid complex compounds of La(III), Sm(III), Tb(III), Dy(III), Ho(III) and Er(III) ions with morin were obtained. They were characterized by elemental analysis, thermogravimetric studies and spectrophotometric determination of metal ions. The molecular formulae of the compounds are: Ln(C15H9O7)3_nH2O, where n = 6 forLa,Sm,Tb,Dy and n = 5 for Ho and Er. Low molar conductances of the complexes (which correspond to non-electrolytes) and the _-_* bands of ligand and the CT bands L_Min UV-VIS spectra of the methanol solutions of the complexes were established. On the basis of 13CNMR and IR spectra, it was supposed that morin was bound to the lanthanide ions via C(4)=O and C(3)-oxygen.
