A series of rare-earth luminescent complexes {[Eu(pta)(H2O)3]center dot H2O}n (1, H3pta=pyridine-2,4,6-tricarboxylic acid) and {[EuxY(1-x)(pta)(H2O)3]center dot H2O}n (210) have been synthesized. Complexes 1 and 8 were determined by single-crystal X-ray diffraction, while other complexes were characterized by powder X-ray diffraction, displaying the similar structural mode. The luminescent properties of complexes 110 were investigated and the results show that the emission intensities of mixed rare-earth complexes 210 are the same or even higher than that of homometallic complex 1 with the increasing Y(III) ions.
