Bis(4-amino-1-hexylpyridinium) bis(1,2-dicyanoethene-1,2-dithiolato)cuprate(II)

Abstract

The complete complex anion in the title salt, (C11H19N2)2[Cu(C4N2S2)2], has 2/m symmetry while the complete cation is generated by mirror symmetry with the non-H atoms of the alkyl chain lying on the plane. A square-planar geometry based on an S4 donor set is found in the anion; the Cu—S distance is 2.2663 (5) Å. In the crystal, intermolecular N—H...N hydrogen bonds link the ions into layers in the bc plane comprising alternating rows of cations and anions.
