Abstract: A new ion-pair complex, (C₁₄H₁₇N₂)₂[Ni(C₄N₂S₂)₂] or (BzDMAP)₂[Ni(i-mnt)₂], where BzDMAP is 1-benzyl-4-(dimethylamino)pyridinium and i-mnt is 2,2-dicyanoethylene-1,1-dithiolate, has been prepared. The [Ni(i-mnt)₂]^2- anion, which is located on an inversion center, exhibits a planar structure. The crystal packing is governed by short C-HN and C-HS contacts between anions and cations and by - stacking interactions between the phenyl groups of the cations (the centroid-centroid distance is 3.802 Å; symmetry code: -x + 2, -y + 2, -z).
