- Abstract
A new nine-coordinated Yb(III) complex [YbL3(Phen)] (1) (HL = 2-(4-acetylphenoxy)acetic acid (APA), Phen = 1,10-phenanthroline) was synthesized with 2-(4-acetylphenoxy)acetic acid, YbCl3.6H2O, NaOH and 1,10-phenanthroline as materials. Complex (1) was characterized by IR and X-ray single-crystal diffraction analysis. The results show that the Yb(III) ion is nine-coordinated with seven carboxylate oxygen atoms from five different deprotonated APA ligands and two nitrogen atoms from one Phen ligand. Complex (1) forms a 3D supramolecular framework through the π-π stacking interactions between the Phen aromatic rings, The Hirschfeld surface analysis of complex (1) was also calculated. The CO2 photoconversion activity of complex (1) has been performed under UV-vis light irradiation. The complex (1) shows good photocatalytic activity with the yield of CO is closed to 146 μmol/g after three hours of UV-vis light irradiation, the CO selectivity has reached to 97.9%.
