Gueye, Mbosse Ndiaye published the artcileLanthanide(III) complexes with tridentate schiff base ligand, antioxidant activity and X-ray crystal structures of the Nd(III) and Sm(III) complexes, Application In Synthesis of 2215-33-0, the publication is South African Journal of Chemistry (2017), 70(1), 8-15, S1-S6, database is CAplus.
The tridentate N4-type Schiff base was synthesized from the condensation reaction of 2-hydrazinopyridine and pyridine-2-carbaldehyde. Neodymium and samarium complexes were isolated when the corresponding nitrate salt was added to the solution of the ligand. The isolated compounds were characterized by elemental analyses, IR study, room temperature magnetic measurements and single x-ray crystal diffraction of the two crystals. Both complexes crystallize in the monoclinic system with space group P21/c. The cell parameters of the Nd complex are a 11.0927(8), b 17.9926(13) Å, c 11.9395(9) Åand β 115.274(5)° while the Sm complex shows parameters cell of a 11.0477(8), b 17.9254(13), c 11.9149(8) Å and β 115.489(5)°. The x-ray study reveals isotopic Nd/Sm binuclear structures were each metal ion is nine-coordinated in the same fashion. Both metal centers have distorted tricapped trigonal prism geometry, with the Schiff base acting as tridentate ligand. The DPPH• radical scavenging effects of the Schiff base ligand and its Ln(III) complexes were screened. The Ln(III) complexes were significantly more efficient in quenching DPPH• than the free Schiff base ligand.
