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—H...O hydrogen bonds into C(6) chains along [100]. The cations and anions are linked into a three-dimensional architecture by weak C—H...N and C—H...S interactions.
