4-(Dimethylamino)pyridinium tetrachlorido(pyridine-2-carboxylato-κ² N,O)stannate(IV)

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.003 Å; R factor = 0.020; wR factor = 0.049; data-to-parameter ratio = 19.2.The reaction of 4-(dimethylamino)pyridine, picolinic acid and stannic chloride yields the title salt, (C 7 H 11 N 2 )[SnCl 4 -(C 6 H 4 NO 2 )], in which the Sn IV atom is N,O-chelated by the picolinate ion in a cis-SnNOCl 4 octahedral geometry. The cation is linked to the anion by an N-HÁ Á ÁO hydrogen bond. Related literature
