| Abstract: | The present report deals with the synthesis of the two MOFs of respective formula {Nd2(L)3(DMF)2(H2O)2]· 2DMF}n (1) and {Gd2(L)3(DMF)2(H2O)2]·2DMF}n (2) were synthesized by solvothermal method using 2,5-dibromo-terephthalic acid (H2L) as a ligand and reacting with neodymium nitrate hexahydrate and gadolinium nitrate hexahy-drate, respectively. The structures of both of them were elucidated by single-crystal X-ray diffraction and powder X-ray diffraction to demonstrate that complexes 1 and 2 crystallize in a similar space group P1 as a triclinic system with high crystal purity. Meanwhile, the complexes were characterized by elemental analysis, IR spectroscopy, UV-Vis absorption spectroscopy, fluorescence, and thermal analysis. Single-crystal X-ray diffraction analysis demon-strates the complexes are connected to the ligand with rare earth ions as metal nodes, forming an infinitely extended 3D network structure. |
