At room temperature, four complexes Ln(Hsal)2(hq) (Ln = La(III), Ce(III), Pr(III), Y(III), Hsal- = C6H4(OH) COO-, salicylateanion; hq- = C9H 6NO-, 8-hydroxyquinoline anion) were successfully synthesized by a solid-state reaction. These complexes were further characterized by elemental analyses, electrical conductance in non-aqueous solvents, x-ray powder diffraction, IR and TG-DTA. IR spectra showed that the rare earth ions are not only coordinated by the oxygen atom from the COO group, but also by the nitrogen atom and oxygen atom of 8-hydroxyquinoline. TG-DTA showed that the stability of the four complexes is better than that of sodium salicylate and 8-hydroxyquinoline. These results show good agreement with results of the literature. The unit cells of the complexes at room temperature have been determined by x-ray powder diffraction (XRD). The crystals of all four complexes belong to the triclinic system and P1 space group. Unit cell parameters were found by using trial and error methods.
