Utilizing proton transfer to produce mol­ecular salts in bromanilic acid substituted-pyridine mol­ecular complexes – predictable synthons?

Proton transfer systematically producing mol­ecular salts is used in a study of nine mol­ecular complexes of bromanilic acid with methyl­pyridines, which show predictable synthons related to the stoichiometry and a common N—H...O charge-assisted hydrogen bond.
