制备新化合物[(NC)Ru2(ap)4]2(μ-1,4-C6H4)（ap = 2-苯胺基吡啶酸酯）是为了解决1,4-亚苯基桥是否可以介导金属间电子耦合这一悬而未决的问题。作为强耦合的表现，使用光谱电化学在红外时间尺度（10−14 s）上建立了 Ru2 中心之间的空穴离域。通过 DFT 分析详细阐述了耦合的轨道机制。
The new compound [(NC)Ru2(ap)4]2(μ-1,4-C6H4) (ap = 2-anilinopyridinate) was prepared to address the open question of whether a 1,4-phenylene bridge can mediate intermetallic electronic coupling. As a manifestation of strong coupling, hole delocalization between the Ru2 centers on the IR time scale (10−14 s) was established using spectroelectrochemistry. An orbital mechanism for coupling was elaborated with DFT analysis.
