A Schiff-base [2 + 2] macrocycle obtained by the reaction of
2,6-diformyl-4-methylphenol with
1,11-diamino-3,9-dimethyl-3,9-diazo-6-oxaundecane encapsulates three
manganese ions into its cavity; EPR, UV–VIS–NIR, XPS
spectroscopic data, X-ray crystallography and magnetic measurements showed
that the metal ions are in a mixed valence state (II,
III, II) which is rare for trimanganese systems.
2,6-二甲酰基-4-甲基苯酚与 1,11-二氨基-3,9-二甲基-3,9-二氮杂-6-氧杂十一烷反应得到的希夫碱 [2 + 2] 大环在其空腔中包覆了三个锰离子;EPR、UV-VIS-NIR、XPS 光谱数据、X 射线晶体学和磁性测量结果表明,金属离子处于混合价态(II、III、II),这在三锰体系中是罕见的。
