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

Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.031; wR factor = 0.074; data-to-parameter ratio = 15.4.The complete complex anion in the title salt, (C 11 H 19 N 2 ) 2 -[Cu(C 4 N 2 S 2 ) 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 S 4 donor set is found in the anion; the Cu-S distance is 2.2663 (5) Å . In the crystal, intermolecular N-HÁ Á ÁN hydrogen bonds link the ions into layers in the bc plane comprising alternating rows of cations and anions. Related literature
