Synthesis,Structures And Characterizations Of Macrocyclic Oxamido Ligands And Their Coordination Compounds

Coordination compounds have attracted a lot of attention because they have showed broad application prospects in gas storage,separation,magnetism,catalysis,optical materials,molecular recognition,and bioscience,which have become an significant intersection of current research in chemistry,materials science,life science and some other fields.The main contents of this dissertation are as follows:1.A new mononuclear macrocyclic oxamido Ni???complex NiL¹ was designed and synthesized.Crystals of Ni L¹ and NiL¹·H₂O were obtained and characterized by elemental analysis,IR spectrum and X-ray single crystal analysis.The compounds were mononuclear and that the zero dimensional molecules were linked into 2D networks through intermolecular hydrogen bonds and ????? interactions.2.A hetero-metallic complex {[Zn₂?NiL²?₂?DACH?₂]·2DMF·H₂O]}n was prepared using macrocyclic complex NiL² as the bridging ligand while DACH acted as a co-ligand.The complex was characterized by IR spectrum and X-ray single crystal analysis.X-ray single crystal analyses revealed that the zero-dimensional compound had box-like structure.3.A hetero-metallic coordination polymer {[Cd?NiL³??H₂O?₂]·2DMF}n that use NiL³ as the bridging ligand was prepared.The coordination polymer was characterized by means of IR,XRD,TG,UV-Vis and etc.X-ray single crystal analyses revealed that it had a 2D extended network structure,which expanded into three-dimensional supramolecular networks through intermolecular hydrogen bonds and ????? interactions.
