Abstract: The asymmetric unit of the title ion-pair complex, (C₉H₁₂NO₂)₂[Ni(C₄N₂S₂)₂], contains two 1-(ethoxycarbonylmethyl)pyridinium cations and one bis(1,2-dicyanoethene-1,2-dithiolato)nickelate(II) dianion, which exhibits a slightly distorted square-planar coordination geometry. In the crystal, the cations are linked by strong C-HO hydrogen bonds into C(6) chains along [100]. The cations and anions are linked into a three-dimensional architecture by weak C-HN and C-HS interactions.
