摘　　要：Utilizing two polycarboxylic acids as primary ligands and 1,10-phenanthrolion as an auxiliary ligand in the existence of lanthanide nitrates, two lanthanide-based complexes formulated as [Nd4（2,6-pydc OH）6（Phen）4（H2O）2]（H2O）2（1） and [Yb2（mBDC）3（Phen）2]n（2）（2,6-H2 pydc OH = 4-hydroxypyridine-2,6-dicarboxylic acid, m-H_2BDC = isophthalic acid, Phen = 1,10-phenanthroline） have been solvothermally synthesized. They have been fully characterized by satisfactory elemental analysis, FT-IR spectra, TGA and single-crystal X-ray diffraction. Single-crystal X-ray diffraction study reveals that 1 has a zero-dimensional structure and 2 exhibits a rare cds topological net structure. Compounds 1 and 2 exhibit strong characteristic emissions of Nd（Ⅲ） and Yb（Ⅲ） ions in the near-infrared（NIR） region.Utilizing two polycarboxylic acids as primary ligands and 1,10-phenanthrolion as an auxiliary ligand in the existence of lanthanide nitrates, two lanthanide-based complexes formulated as [Nd4（2,6-pydc OH）6（Phen）4（H2O）2]（H2O）2（1） and [Yb2（mBDC）3（Phen）2]n（2）（2,6-H2 pydc OH = 4-hydroxypyridine-2,6-dicarboxylic acid, m-H_2BDC = isophthalic acid, Phen = 1,10-phenanthroline） have been solvothermally synthesized.
