摘要: 本文合成了轴水配位的十四元六氮大环Co(Ⅱ)配合物,进行了元素分析、波谱、磁化率及电导等测定,发现该配合物具有反常磁性(室温磁矩为3.13BM),据此我们使用了Co(Ⅱ)离子自旋态的2E-4T1模型,从理论上较好解释了该配合物的反常磁行为。

Abstract: Anew Co(Ⅱ) complex of a 14-Membcrcd hexaaza macrocyclic ligand with the H2Oin axial sites, [CoL(H3O)2](NO3)2, has been prepared and characterized by elemental analysis, spcctroscopoc magnetic, and conductance mcasurcmcnts etc. It has been found that this complex exhibits cnomalous magnctie behavior (magnetic moment is 3.13 BMat room-temperature).The magnetic properties have been excellently interpreted by the 2E-4T1 crossover model.
