不对称取代的邻二甲基四氢呋喃的卤化物盐被组织成具有空间群I-42d的四方结构的均一链，式为(o-DMTTF)2X，X = Cl，BrI，提供了一个罕见的非二聚3/4填充体系的例子。合成了固溶体(o-DMTTf)(Br)x(Cl)1−x和(o-DMTTf)2(Brx)x(I)1−x，并对其结构进行了表征。随着阴离子尺寸的增大，观察到了系统的优先溴插入以及结构的侧向扩展。
Halide salts of the unsymmetrically substituted o‐DMTTF, formulated as (o‐DMTTF)2X, X = Cl, Br, I, are organized into uniform chains in a tetragonal structure with space group I‐42d, providing a rare example of non‐dimerized 3/4 filled system. Solid solutions formulated as (o‐DMTTF)(Br)x(Cl)1−x and (o‐DMTTF)2(Br)x(I)1−x have been prepared and structurally characterized. A systematic preferential bromide insertion is observed together with a lateral expansion of the structure with increasing anion size.
