Bis[4-(dimethylamino)pyridinium] bis(1,2-dicyanoethene-1,2-dithiolato-²S,S')cuprate(II)

H. Zhou and X.-M. Ren

Abstract: In the title salt (C₇H₁₁N₂)₂[Cu(C₄N₂S₂)₂], the Cu²⁺ ion is coordinated by four S atoms of two 1,2-dicyanoethene-1,2-dithiolate (or maleonitriledithiolate, mnt^2-) ligands in an approximate square-planar geometry. The Cu atom is located on an inversion centre. Strong hydrogen-bonding interactions between the pyridinium proton and the CN groups of the mnt^2- ligand link anions and cations into a one-dimensional chain structure.
