N2 - A heteroleptic nickel-bis-1,2-dithiolene ion-pair complex, [BzQl][Ni(dmit)(mnt)] (where BzQl+ = 1-(benzyl)quinolinium; dmit 2- = 2-thioxo-1,3-dithiole-4,5-dithiolate, mnt2- = maleonitriledithiolate), was synthesized and characterized structurally, which exhibited novel magnetic bistability. The compound crystallized in triclinic system with space group P-1. The anions and cations form alternating layered alignments, and the anionic layer is built by the irregularly heteroleptic [Ni(dmit)(mnt)]- chains, where the neighboring anions are connected via lateral-to-lateral S...S contacts of dmit2- ligands. The temperature dependences of magnetic susceptibility follow the S = 1/2 Heisenberg alternating linear-chain model in high-temperature phase and Curie-Weiss law in low-temperature phase.
