A new ion-pair complex, [DiClBzMePy][Ni(mnt)2] (1) ([DiClBzMePy]+ = 1-(2'4'-dichlorobenzyl)-3-methylpyridinium; mnt2- = maleonitriledithiolate), has been prepared. The [image omitted] anion and [DiClBzMePy]+ cations of Complex 1 stack into well-segregated columns in the solid state, and the Ni(III) ions form a 1D zigzag chain within a [image omitted] anion through Ni···S, S···S and Ni···S···Ni interactions. The anion-anion, anion-cation and cation-cation contacts may play important roles in the crystal packing. Variable temperature magnetic susceptibilities measured at 75-300 K reveal that Complex 1 exhibits antiferromagnetic behavior.
