在由二（亚乙基二硫代）四硫富瓦烯（ET）和2，3-二氯-5，6-二氰基对苯醌（DDQ）组成的离子电荷转移（CT）配合物C10 H8 S8·C8 Cl 2N 2 O2中，给体和受体分子均通过强的π-π相互作用形成中心对称的二聚体。无序的DDQ分子形成一维π堆叠柱，而ET分子通过相邻π-π键合的二聚体之间的额外短S S接触形成两条腿的梯子。本研究揭示的ET-DDQ的晶体结构将提供一个有价值的例子，两个腿的自旋梯系统，这是很少报道的ET为基础的CT配合物。
In the ionic charge-transfer (CT) complex composed of bis(ethylenedithio)tetrathiafulvalene (ET) and 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ), C10H8S8·C8Cl2N2O2, the donor and acceptor molecules both form centrosymmetric dimers associated by strong face-to-face π–π interactions. The disordered DDQ molecules form a one-dimensional π-stacked column, while the ET molecules form a two-leg ladder through additional short S⋯S contacts between adjacent π–π-bonded dimers. The crystal structure of ET–DDQ revealed in this study will provide a valuable example of the two-leg spin ladder system, which has rarely been reported for ET-based CT complexes.
