摘要：

A new ion-pair complex, [VBzPy][Ni(mnt)(2)], where [VBzPy](+) = 1-(4'-vinylbenzyl)pyridinium and mnt(2)- = maleonitriledithiolate, has been synthesized. The cations and anions stack into completely separated columns and Ni(III) ions form a uniformly spaced one-dimensional (1-D) zigzag chain within a [Ni(mnt)2](-) column in solid state. Magnetic susceptibility and DSC measurements revealed that there exists a first-order phase transition at approximately 208 K.
