摘要: Abstract Two different types of novel lanthanide coordination polymers constructed from 5-nitroisophthalic acid, and picolinic acid as auxiliary ligand, namely, {[Ln 2 (nip) (pic) (H O)]} n (type I, Ln = Pr 1 , Nd Sm 3 Eu 4 H nip = 5-nitroisophthalic Hpic = picolinic acid), 5 O) ]·2H O} II, Ln = Tb Dy 6 Ho 7 Er 8 ), have been hydrothermally synthesized characterized by IR, elemental analysis, thermogravimetric analysis (TGA), single-crystal X-ray diffraction analyses powder (PXRD). Complexes – I) are isostructural the infinite 1D Sm-carboxylate chains bridged pia ligands to form 2D sheets, such sheets further united together generate a 3D supramolecular structure. II) Tb–carboxylate Furthermore, luminescence properties compounds also studied.
