Novel lanthanide luminescent materials based on complexes of 3-hydroxypicolinic...
Soares-Santos, PCR; Nogueira, HIS; Felix, V; Drew, MGB; Ferreira, RAS; Carlos, LD; Trindade, TNew lanthanide complexes of 3-hydroxypicolinic acid (HpicOH) were prepared: [Ln(H2O)- (picOH)2(í-HpicO)]â3H2O (Ln ) Eu, Tb, Er). The complexes were characterized using photoluminescence, infrared, Raman, and 1H NMR spectroscopy, and elemental analysis. The crystal structure of [Eu(H2O)(picOH)2(í-HpicO)]â3H2O 1 was determined by X-ray diffraction. Compound 1 crystallizes in a monoclinic system with space group P...
