Synthesis, crystal structure, and optical properties of a novel rare-earth complex Nd(C2F5COO)3 · Phen

Abstract

A novel neodymium pentafluoropropionate binuclear complex, Nd(C 2 F 5 COO) 3 Á Phen (Phen: 1,10-phenanthroline), was synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, FT-IR spectra, UV-Vis-NIR absorption, and PL spectra. Singlecrystal data show that the complex bears centrosymmetric dinuclear structure with a planar ligand configuration. Four carboxylato groups act as g 2 -chelate-l 2 -carboxylato-k 1 O: k 1 O 0 -bridge-ligands, the other two occupy the terminal position as monodentate ligands. At the same time, the C-O distances appear averaged which indicate the three atoms of carboxylato forming electron-conjugate system. Hydrogen bond and p-p-stacking link the binuclear to two-dimensional sheet. Optical spectra exhibit the complex possesses typical Nd(III) ion absorption and photoluminescence emission.

“…Lanthanide complexes have applications as functional materials due to their unique physicochemical properties such as magnetism, electroluminescence, and photoluminescence [290]. The following paper discusses the synthesis by She et al [290] of a novel neodymium pentafluoropropionate binuclear complex: Nd(C 2 F 5 COO) 3 Á Phen, where Phen is 1,10-phenanthroline.…”
