3.5- dinitrobenzoic acid, ternary

Figure 8.45 Ternary co-crystal of the ditopic supramolecular coupling reagent 8.41 with two benzoic acid derivatives. The stronger 3,5-dinitrobenzoic acid interacts with the stronger imidazole base while the second best acid, 4-nitrobenzoic acid interacts with the second best pyridyl base.
