Abstract:A 2D Nd(Ⅲ) coordination polymer ,[Nd(5‐OH‐BDC)(5‐OH‐HBDC)(H2 O)2 ]n · 2nH2 O (1) , has been obtained by assembly of Nd (NO3 )3 · 6H2 O and 5‐hydroxyisophthalic acid (5‐OH‐H2BDC) under hydrothermal condition .Complex 1 was characterized by elemental analysis ,infrared spectroscopy ,thermogravimetric analysis ,as well as powder and single‐crystal X‐ray diffraction analy‐ses .Single‐crystal X‐ray diffraction analysis reveals that two adjacent Nd(Ⅲ ) ions in complex 1 are bridged by two [5‐OH‐BDC ]2 - ligands to form a dinuclear [Nd2 (CO2 )8 ] secondary building unit (SBU) ,which are further linked by [5‐OH‐BDC]2 - ligands to yield a 2D layer structure with a (3 ,6)‐connected kgd topology .In addition ,the solid‐state photoluminescence property reveals that complex 1 shows a strong characteristic emission of Nd(Ⅲ) in the near‐infrared region upon excitation at 350 nm .
