Synthesis, structure, and luminescent property of a novel cadmium (II) carboxyphosphonate with a 2D layered structure using 1,4-benzenedicarboxylic acid as second linker

► A novel cadmium(II) carboxyphosphonate with a 2D layered structure has been synthesized under hydrothermal conditions. ► Compound 1 is the first example of cadmium phosphonates with 2D layered structure using H2O3PCH2NC5H9COOH (H3L) as ligand. ► The luminescent analysis indicates that the use of H2bdc may be an effective way to prepare blue luminescent materials.
