Diruthenium(II,II) Complex Assemblies Showing Electrical Conduction via π‐Stacked 2‐Pyrenecarboxylate Moiety
Through-space electrical conduction in paddlewheel-type homovalent dinuclear complexes remains poorly understood, despite the numerous reports on these complexes. Herein, the electrical conduction of new Ru<sub>2</sub>(II,II) complexes with 2-pyrenecarboxylate (pyrCOO<sup>-</sup>) ligands, [Ru<sub>2</sub>(pyrCOO)<sub>4</sub>X<sub>2</sub>] ⋅ n(X) (where X=DMF (Ru-DMF), NMP (Ru-NMP), DMA (Ru-DMA)), was investigated. The dimensionality of π-stacking interactions between discrete molecules in Ru-DMA is higher (two-dimensional) than in Ru-DMF and Ru-NMP (stair-like one-dimensional). Nevertheless, Ru-DMF, which contains a slight amount of organic radicals, exhibited the highest electrical conductivity. This suggests that the large overlap and high dimensionality of π-stacking interactions among the complexes, along with a slight organic radical impurity, contribute to the increased electrical conductivity.
