4-(Dimethylamino)pyridinium tetrachlorido(quinoline-2-carboxylato-κ²N,O)stannate(IV)

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.003 Å; R factor = 0.021; wR factor = 0.047; data-to-parameter ratio = 18.4.In the title salt, (C 7 H 11 N 2 )[SnCl 4 (C 10 H 6 NO 2 )], the Sn IV atom is chelated by the N,O-bidentate carboxylate ions and four chloride ions, showing a distorted octahedral SnNOCl 4 coordination. In the crystal, the cation and anion are linked by a pyridinium-carboxylate N-HÁ Á ÁO hydrogen bond. Related literature

“…A previous study reported 4-(dimethylamino)pyridinium tetrachlorido(quinoline-2-carboxylato)stannate, which was synthesized by the reaction of 4-(dimethylamino)pyridine, quinoline-2-carboxylic acid and stannic chloride in methanol (Najafi et al, 2011). The reaction with picolinic acid in place of quinoline-2-carboxylic acid yielded the analogous salt, (C 7 H 11 N 2 )[SnCl 4 (C 6 H 4 NO 2 )] (Scheme I).…”
