Two hydration products of 3,4,5,6‐tetrachloro‐
In 2‐amino‐6‐methylpyridin‐1‐ium 2‐carboxy‐3,4,5,6‐tetrachlorobenzoate, C6H9N2 +·C8HCl4O4 −, there are two perpendicular chains of hydrogen‐bonded ions, one arising from the interaction between 2‐carboxy‐3,4,5,6‐tetrachlorobenzoate ions and the other from the interaction between the 2‐amino‐6‐methylpyridin‐1‐ium and 2‐carboxy‐3,4,5,6‐tetrachlorobenzoate ions. These chains combine to form a two‐dimensional network of hydrogen‐bonded ions. Cocrystals of bis(2‐amino‐3‐methylpyridin‐1‐ium) 3,4,5,6‐tetrachlorophthalate–3,4,5,6‐tetrachlorophthalic acid (1/1), 2C6H9N2 +·C8Cl4O4 2−·C8H2Cl4O4, form finite aggregates of hydrogen‐bonded ions. π–π interactions are observed between 2‐amino‐3‐methylpyridin‐1‐ium cations. Both structures exhibit the characteristic R 2 2(8) motif as a result of the hydrogen bonding between the 2‐aminopyridinium and carboxylate units.
