1-D to 3-D lanthanide coordination polymers constructed from 5-aminoisophthalic acid and oxalic acid

► The X-ray single-crystal structures of 1-3 are obtained and analyzed in detail. ► lanthanide complexes 1-3 containing the mixed ligands of H2AIP and H2OX are very rare so far. ► The fluorescent spectra of 2 is measured and analyzed in detail.
