2,2‘;9‘,2‘ ‘-Ter[1,10]phenanthroline

The title molecule, 2,2‘;9‘,2‘ ‘-ter[1,10]phenanthroline can be
prepared from 2,9-dichloro-1,10-phenanthroline in three steps
through the corresponding diacetyl intermediate. The ligand acts
as a hexadentate with K+, while two molecules form a trinuclear,
helical complex with Cu(I), which evidences π-stacking interactions
and Cu−Cu distances of 3.01−3.04 Å. Electrochemical analysis
shows a strong interaction between the Cu(I) centers.

标题化合物2,2‘;9‘,2‘−ter[1,10]菲咯啉可通过三步反应从2,9-二氯-1,10-菲咯啉制备而成，反应过程中涉及相应的二乙酰中间体。该配体在与K+作用时表现出六齿配位特性，而两个分子与Cu(I)形成三核螺旋复合物，这证实了π-堆积相互作用以及Cu−Cu间距为3.01−3.04埃。电化学分析表明，Cu(I)中心之间存在强烈的相互作用。
