Such as nonlinear optical,?magnetic,?ion exchange,?adsorption,?catalysis,?chemical sensing?has aroused extensive attention,?and it has become a hot topic?in chemistry,?material science,?life science?and other fields. Among various organic ligands, multicarboxylate ligands are often used as multifunctional ligands because their various coordination modes and deprotonation of carboxylic groups, which may have a significant influence on crystalline structures. Moreover, the various coordination modes and ability can act as H-bond acceptors and donors, this weak interaction is significantin assemblingsupramolecular networks. In this paper, we select organic polycarboxylic acid as a primary ligand ，and a transition metal ion coordination polymer synthesis,We used the X- ray carried out structure, and by elemental analysis, infrared spectroscopy (IR), X- ray diffraction (PXRD), thermal stability analysis (TGA) and other characterization was carried out accordingly. And with fluorescent, magnetic and adsorption performance is further possible were tested and analyzed to want unique structure and coordination polymers have special functions. . We u
