Crystal structure of the co-crystal salt 2-amino-6-bromo-pyridinium 2,3,5,6-tetra-fluoro-benzoate.

ABSTRACT: The asymmetric unit of the co-crystal salt 2-amino-6-bromo-pyridinium 2,3,5,6-tetra-fluoro-benzoate, C₅H₆BrN₂ ⁺·C₇HF₄O₂ ^-, contains one pyridinium cation and one benzoate anion. In the crystal, the amino-pyridinium cationic unit forms two hydrogen bonds to the benzoate oxygen atoms in an R ₂ ²(8) motif. Two pyridinium benzoate units are hydrogen bonded through self-complementary hydrogen bonds between the second amine hydrogen and a carboxyl-ate O with a second R ₂ ²(8) motif to form a discrete hydrogen-bonded complex containing two 2-amino-6-bromo-pyridinium moieties and two 2,3,5,6-tetra-fluoro-benzoate moieties. The 2-amino-6-bromo-pyridinium
