Facile Solid-State Chemical Synthesis of Novel Ternary Lanthanide Complexes at Room Temperature

Abstract

This paper reports a facile one-step synthesis of two ternary lanthanide complexes via room temperature solid-state reactions of lanthanide chloride hydrates with two ligands, potassium sorbate (PS), and 8-hydroxyquinoline (8-hq). The structural features, composition, and the morphologies of two complexes are characterized by elemental analysis, UV-Vis, FT-IR, XRD, SEM, and EDX. The thermal property of two ternary lanthanide complexes was also investigated. UV-Vis and FT-IR results confirm the coordination of lanthanide ion with two ligands. XRD results show that signals of complexes are not from reactants, and are believed to originate from the corresponding ternary lanthanide complex.
