本文以CoCl_2为模板盐,用2,6-二乙酰吡啶肼缩合制得一个新的轴Cl~- 配位的十四元六氮大环 Co(Ⅱ)配合物[CoLCl_2]·2H_2O.经元素分析、波谱、磁化率及电导测定,推定该配合物为六配位的畸变八面体构型.配合物的实测磁矩(4.16BM)略低于理论值(5.2BM),据此并讨论了偏低的原因以及轴配场强度与中心离子Co(Ⅱ)高低自旋态的关系.此外,还从电子光谱数据用配位场方法评价出了D_q,B,β,等数值和谱带的位置,结果理论值与实验值相当吻合。
In this paper, CoCl_2 was used as a template salt to synthesize a new 14-membered cyclic hexagonal macrocyclic Co (Ⅱ) complex [CoLCl_2] · 2H_2O with Cl 2 -acetylpyridine hydrazide. Analysis, spectra, magnetic susceptibility and conductivity measurements, the complex is assumed to be a six-coordinated distorted octahedral configuration.The measured magnetic moment (4.16BM) of the complex is slightly lower than the theoretical value (5.2BM) And the relationship between the intensity of the field distribution and the high and low spin states of the central ion Co (Ⅱ). In addition, the values of D_q, B, β and other bands and bands Position, the theoretical results and experimental values quite consistent.
