Bis(4-dimethylamino-1-ethylpyridinium) bis(1,2-dicyanoethene-1,2-dithiolato-²S,S')nickelate(II)

S.-S. Yu, H. Zhou and X.-M. Ren

Abstract: The asymmetric unit of the title complex, (C₉H₁₅N₂)₂[Ni(C₄N₂S₂)₂], comprises one 4-dimethylamino-1-ethylpyridinium cation and one half of a [Ni(mnt)₂]^2- (mnt^2- = maleonitriledithiolate) anion; the complete anion is generated by the application of a centre of inversion. The Ni^II ion is coordinated by four S atoms of two mnt^2- ligands and exhibits a square-planar coordination geometry.
