title: Bis[1-(eth-oxy-carbonyl-meth-yl)pyridinium] bis-(1,2-dicyano-ethene-1,2-dithiol-ato-κ(2)S,S')nickelate(II).
abstract: The asymmetric unit of the title ion-pair complex, (C(9)H(12)NO(2))(2)[Ni(C(4)N(2)S(2))(2)], contains two 1-(eth-oxy-carbonyl-meth-yl)pyridinium cations and one bis-(1,2-dicyano-ethene-1,2-dithiol-ato)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 inter-actions.
