A new Cr(III) bis-acetylide complex containing redox-active ethynyl-substituted 4-methyl-4′,5′-trans-diethyl-ethylenedithio-tetrathiafulvalene, [Cr(III)cyclam(C≡C-MeEt₂EDT-TTF)₂]ⁿ⁺ ([1]ⁿ⁺) was synthesized. The crystal structures of two salts, [1][Ni(dmit)₂] (dmit = 2-thioxo-1,3-dithiole-4,5-dithiolate) and [1][Ni(mnt)₂]₃ (mnt = maleonitriledithiolate), were determined by single-crystal X-ray diffraction. In the crystal of [1][Ni(dmit)₂], the trans-diethyl group of [1]⁺ is in the axial position and prevents π-stacking of the TTF units, resulting in a negligibly weak spin–spin interaction between Cr³⁺ and [Ni(dmit)₂]⁻. In contrast, in [1][Ni(mnt)₂]_3, the trans-diethyl group is in the equatorial position in [1][Ni(mnt)₂]₃ owing to the strong attractive force between the π-stacked TTF⁺ units and the [Ni(mnt)₂]⁻ anions. This π-stacking has a significant effect on the magnetic property of [1] [Ni(mnt)₂]₃. The π-stacked TTF⁺ units and [Ni(mnt)₂]⁻ anions behave approximately as a one-dimensional S = 1/2 antiferromagnetic chain connecting the spins of Cr³⁺ antiferromagnetically.
