region 1663–1698 cm −1 . The nitrosyl iron complexes had sub-normal magnetic moments at room temperature and showed two v NO bands. Based on the measurements of magnetic moments in the temperature range 80–300 K, these complexes were revealed to be in a spin equilibrium between the s = 3 2 and s = 1 2 states. NO frequencies and ESR parameters of the complexes were discussed in terms of electron-with-drawing
摘要亚硝酰基钴和亚硝酰基铁配合物Co-(JR)NO(R = en,pn,ph),Fe(JR)NO(R = ph,mph)和Fe(bza-ph)NO合成,其中H 2(J–R)是具有桥接基团R(en =乙烯; pn = 1,2-丙烯; ph =邻苯撑; mph = 4-甲基-邻苯撑)的Jager型配体,将两个亚氨基氮和H 2(bza-ph)是N,N'-双(2-苯甲酰基亚乙基)-邻苯二胺。Co(J–R)NO在1663–1698 cm -1区域显示NO拉伸带。亚硝酰基铁配合物在室温下具有低于正常的磁矩,并显示出两个v NO带。根据在80-300 K温度范围内的磁矩的测量结果,发现这些络合物处于s = 3 2和s = 1 2状态之间的自旋平衡。
