Podjed, Nina published the artcileHydrogen Bonding and Polymorphism of Amino Alcohol Salts with Quinaldinate: Structural Study, Name: 2-Aminobutan-1-ol, the publication is Molecules (2022), 27(3), 996, database is CAplus and MEDLINE.
Three amino alcs., 3-amino-1-propanol, 2-amino-1-butanol and 2-amino-2-methyl-1-propanol were reacted with quinoline-2-carboxylic acid, known as quinaldinic acid. This combination yielded three salts, I [R = 3-hydroxypropylammonium, 1-hydroxymethyl propylammonium, 2-hydroxy-1,1-dimethyl-Et ammonium]. The 2-amino-1-butanol and 2-amino-2-methyl-1-propanol systems produced two polymorphs each, labeled as salts I [R = 1-hydroxymethyl propylammonium, 2-hydroxy-1,1-dimethyl-Et ammonium] resp. The compounds were characterized by X-ray structure anal. on single-crystal. The crystal structures of all consisted of protonated amino alcs. with NH3+ moiety and quinaldinate anions with carboxylate moiety. The used amino alcs. contained one OH and one NH2 functional group, both proned to participate in hydrogen bonding. Therefore, similar connectivity patterns were expected. This proved to be true to some extent as all structures contained the NH3+•••–OOC heterosynthon. Nevertheless, different hydrogen bonding and π•••π stacking interactions were observed, leading to distinct connectivity motifs. The largest difference in hydrogen bonding occurred between polymorphs , I [R = 2-hydroxy-1,1-dimethyl-Et ammonium] as they had only one heterosynton in common.
