摘　　要：A series of rare-earth luminescent complexes {[Eu（pta）（H2O）3]·H2O}n（1, H3pta=pyridine-2,4,6-tricarboxylic acid） and {[EuxY（1-x）（pta）（H2O）3]·H2O}n（2-10） 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 1--10 were investigated and the results show that the emission intensities of mixed rare-earth complexes 2--10 are the same or even higher than that of homometallic complex 1 with the increasing Y（Ⅲ） ions.A series of rare-earth luminescent complexes {[Eu（pta）（H2O）3]·H2O}n（1, H3pta=pyridine-2,4,6-tricarboxylic acid） and {[EuxY（1-x）（pta）（H2O）3]·H2O}n（2-10） have been synthesized.
