Besides, it’s also has a great significance for people to look for better model compounds to do biological functional tests. This dissertation, conducted from a comparative perspective, summarizes a certain amount of papers and reports related to Manganese organic acid complexes’ structual types , character researches as well as it’s compounds methods . Meanwhile, work in this paper obtained on the synthesis of Mn (II) coordination polymers were x-ray diffraction, infrared spectroscopy, thermal and chemical properties such as the characterization. In ethanol / water mixed solvents, when Mn (II), Pyridine-2,3,5,6-tetracarboxylate (H4pdtc) and 2,2 - bipyridine (bpy) assembled automatically, then a Mn (II) coordination polymer: [Mn (bpy) 2 (H2pdtc)] will come into being. The complex belongs to monoclinic, P2 (1) / n space group, a = 7.7
