HPLC of Formula: 3685-23-2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Investigating the Stability of Double Head to Tail Dimers and Ribbons in Multicomponent Crystals of cis-4-Aminocyclohexanecarboxylic Acid with Water and Oxalic Acid.

The current contribution aims to study the stability of commonly occurring motifs present in certain amino acid structures after introducing addnl. mols. to form multicomponent crystals. The crystal structures of the amino acid cis-4-aminocyclohexanecarboxylic acid hemihydrate I and dehydrate II forms and that of its oxalate salt cocrystd. with oxalic acid III, were studied employing a combination of techniques. Both single-crystal and powder x-ray diffraction were used to solve the structures, while temperature-control powder X-ray diffraction was used to follow the dehydration of I. Regardless of the added mols. that induce modifications of the intermol. interactions within the crystals, some recurring supramol. structures were identified: double head to tail dimers, graph symbol R22(16), and ribbons, graph symbol R22(16)R34(10). Stabilities of these supramol. motifs were studied using theor. modeling with DFT/B3LYP/6-31++G (d,p) and PM6-D2H calculations The theor. calculations reproduced the exptl. findings, confirming the extraordinary stability of these motifs. The mol. recognition of amino acid pairs to form double head to tail-dimers is undoubtedly the initial driving force for the crystal formation in all the three crystals studied.
