dc.description.abstractSix new multi-component crystals between 4-phenylpyridine and substituted benzoic acids (3-nitrobenzoic acid, 3,5-dinitrobenzoic acid, gallic acid, 4-aminobenozic acid, salicylic acid and 2-aminobenzoic acid) were created and characterized crystallographically to investigate the influence of chemical and structural factors on the hydrogen location between the two components. While the expected intermolecular interactions are formed between the acid and pyridine group in most cases, the gallic acid structure is anomalous forming an unexpected salt with pyridine to hydroxyl interactions. Calculations of the hydrogen bonding motifs indicate that the level of proton transfer (e.g. salt versus co-crystal formation) is not solely a function of the dimer geometry but influenced by the local crystallographic environment. Analysis of the crystal structures indicates the strength of the hydrogen bonding into this motif alters the expected protonation state from chemical considerations.en
