Abstract

Lanthanide coordination complexes [Er(H₃thaea)₂](NO₃)₃·2H₂O·2CH₃OH (1) and [Yb(H₃thaea)₂](NO₃)₃·2H₂O·2CH₃OH (2) were prepared by the reaction of Er(NO₃)₃·5H₂O or Yb(NO₃)₃·5H₂O with tris(((2-hydroxy-3-methoxybenzyl)amino)ethyl)amine (H₃thaea) in methanol. The complexes were characterized by elemental analysis, spectroscopy, photoluminescence, and single crystal X-ray diffraction. The erbium(III) ion of 1 is coordinated by six oxygen atoms of two H₃thaea ligands and shows a nearly octahedral geometry structure. The coordinated oxygen atoms are deprotonated (O⁻) and three secondary nitrogen atoms of H₃thaea are protonated ((-CH₂)₂NH₂ ⁺). Complex 2 shows almost the same structure to that of 1. Complex 1 exhibits three emission peaks in near IR region due to Er(III) ion at 973, 1013, and 1233 nm, while complex 2 displays one sharp emission at 977 nm with broad band from 920 to 1100 nm due to Yb(III) ion.
