Abstract

Nine ion-pair compounds [C_n-Apy]₂[Ni(mnt)₂] (C_n-Apy⁺ = 1-alkyl-4-aminopyridinium, n = 2-10, corresponding to compounds 1-9; mnt^2-= maleonitriledithiolate) were synthesized and characterized structurally. The hydrocarbon chain in the countercation adopts all trans-plane conformation when n < 7; otherwise, it adopts the mixed trans and gauche conformation. 1, 2, 8, and 9 show the layered packing structure of alternating anions and cations, whereas 3-6 display the mixed stacking structure of anions (A) and cations (C) in a… ACCA… manner. 3-9 exhibit the thermotropic liquid crystal behaviors. The redox couple of [Ni(mnt)₂]⁻/[Ni(mnt)₂]^2-in the solid state depend on the hydrocarbon chain length in the cation. [Supplemental materials are available for this article.
