Syntheses, Structure, and Luminescent Property of a New 2D Nd(III) Coordination Polymer Based on 4′-(4-Carboxyphenyl)-4,2′:6′,4″-Terpyridine

详细

A new lanthanide coordination polymer (Ln-CP) based on Nd(III), [Nd₂(Cptpy)₂(Glu)₂(H₂O)₂]_n · 5n(H₂O) (Ι) (HCptpy = 4′-(4-carboxyphenyl)-4,2′:6′,4″-terpyridine and H₂Glu = glutaric acid), have been hydrothermally synthesized and characterized by elemental analysis, IR, single crystal X-ray diffraction (CIF file CCDC no. 1857154) and thermal analyses. Single crystal X-ray analysis (CIF file CCDC no. 1857154) reveals that compound Ι displays a (4,5)-connected 2D topological net and the Schläfli symbol of (3.4³.5²)(3².4⁴.5².6²), which is further extended into a 3D supramolecular network by hydrogen bonds. Additionally, the near-infrared (NIR) luminescence of Ι was investigated in the solid state at room temperature.
