Halide salts of the unsymmetrically substituted o ‐DMTTF, formulated as ( o ‐DMTTF) 2 X, 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.Tetragonal (space group I–42d) structure of the halide salts of o ‐DMTTF, in solid solutions ( o ‐DMTTF) 2 (X) x (Y) 1− x .
