摘要: The preparation and characterization of a novel mixed metal complex europium (III) terbium tripodal heptadentate Schiff-base ligand N [CH2CH2N=CH (2-OH-3-MeC6H3)]3 (H3L1) have been studied. was prepared by the reaction [EuL1] [TbL1] in N, N-dimethylformamide. ratio to found be 3 7. molecular structure [Eu0.3Tb0.7L1] determined X-ray crystallography. crystal analysis revealed that behaves as tri-deprotonated encapsulating each ion within N4O3 cavity. Under excitation UV light, solid state exhibited red emission corresponding ion. bands 5D0 → 7Fj (j = 2, 3, 4) were observed at 609, 652, 706 nm, respectively. On other hand, green not observed.
