摘要

Two new ion-pair complexes [1-(4′-fluorobenzyl)pyridinium][Ni(bdt)₂] (1) and [1-(4′-bromobenzyl)pyridinium][Ni(bdt)2] (2), in which bdt^2- = 1,2-benzenedithiolate ('S₂'^2-), have been prepared and characterized. X-ray structural analyses showed that 1 and 2 are isostructural, and the anions are centrosymmetric. The 2 non-equiv. anions form different uniform-spaced stacking pattern in 1 and 2. The magnetic measurements of 1 and 2 indicate ferromagnetic behavior in the antiferromagnetic exchange system, which may arise from spin canting. Cyclovoltammetry revealed two quasi-reversible one-electron steps for 1 and 2, which are attributed to Ni(IV/III) and Ni(III/II) redox couples.
