4-Cyano-1-(4-nitrobenzyl)pyridinium bis(2-thioxo-1,3-dithiole-4,5-dithiolato-κ²S⁴,S⁵)nickelate(III)

Abstract

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.005 Å; R factor = 0.040; wR factor = 0.090; data-to-parameter ratio = 14.0.In the title salt, (C 13 H 10 N 3 O 2 )[Ni(C 3 S 5 ) 2 ], the Ni III cation is S,S 0 -chelated by two 2-thioxo-1,3-dithiole-4,5-dithiolate anions in a distorted square-planar geometry. The complex anion is approximately planar with a maximum deviation of 0.097 (1) Å . In the 1-(4-nitrobenzyl)-4-cyanopyridinium cation, the pyridine ring is twisted at a dihedral angle of 73.84 (16) with respect to the benzene ring. -stacking is observed between nearly parallel [dihedral angle = 4.71 (7) ] dithiole and benzene rings, the centroid-centroid distance being 3.791 (2) Å .
