摘要
金属有机磁性材料在电子磁性开关方面具有潜在的应用.以DMF/水为溶剂(DMF=N,N-二甲基甲酰胺),5-(4′-羧基苯氧基)烟酸为配体,采用溶剂热法合成了新型金属有机磁性材料:[Co(cpna)(H_2O)_2]n(H_2cpna=5-(4′-羧基苯氧基)烟酸).利用单晶X-射线衍射(SCXRD)、红外光谱(FTIR)、热重分析(TG)等对其结构进行分析与表征.结果表明,这种新型3D金属有机配位聚合物是因为配体中—O—扭转角度的灵活而形成波浪状柔性三维网络结构,该配合物属于单斜晶系,P-1空间群,并且有较高的热稳定性.
Metal-organic magnetic materials have potential applications in electronic magnetic switch.A novel metal-organic magnetic material is synthesized by solvothermal method using DMF/water as solvent （DMF=N,N-dimethylformamide） and 5-（4′-carboxyphenoxy）nicotinic acid as ligands.[Co（cpna）（H 2O） 2] n （H 2cpna=5-（4′-carboxyphenoxy）nicotinic acid）.Its structure was analyzed and characterized by using single crystal X-ray diffraction （SCXRD）, infrared spectroscopy （FTIR）, thermogravimetric analysis （TG）. The results show that this new type of 3D metal organic coordination polymer is a wavy flexible three-dimensional network structure formed due to the flexibility of the —O— torsion angle of the ligand. The complex belongs to the monoclinic structure, crystalline, P-1 space group, and has high thermal stability.
