the backbone of the macrocycle. The structures of the two macrocycles have been elucidated by X-ray diffraction, and both adopt planar conformations due to the tautomerization of the internal hydrogen atoms to meso nitrogen positions. The Ag I complexes of both rings are also presented, and the structures of both complexes Ag2 and Ag3 have also been elucidated by single-crystal X-ray methods. In both
酞菁变体 dicarbahemiporphyrazine (1) 的合成遵循简单的席夫碱缩合协议,并且可以很容易地进行修改以将各种修饰的苯环并入大环中。在本报告中,我们介绍了二羟基二氨基四氮杂卟啉 (2) 和四羟基二氨基四氮杂卟啉 (3) 的合成,其中两个苯酚和两个间苯二酚基团分别被纳入大环的骨架。两个大环的结构已通过 X 射线衍射阐明,由于内部氢原子互变异构化到中间氮位置,两者均采用平面构象。还呈现了两个环的 Ag I 配合物,并且还通过单晶 X 射线方法阐明了配合物 Ag2 和 Ag3 的结构。
