Abstract
ABSTRACT Density functional theory (DFT) calculations were made to investigate the interaction between enantiomers of methoxetamine (R & S) and achiral organic reagents, such as oxalate, succinate, fumarate, maleate, glutarate, adipate, pimelate, and suberate anions. The obtained results indicate that the oxalate and maleate anions have a greater ability to form conglomerate crystal of methoxetamine in the gas phase and in solution with chloroform, ethanol, and water. Results of the energy analysis reveal that, in comparison to gas phase and chloroform, the Gibbs energy, enthalpy, and internal thermal energy become more positive in the presence of water and ethanol solvents, confirming the negative effect of solvent polarity on enantiomer separation. It should also be noted that the presence of carbon-chain lengths greater than 3 atoms in organic reagents is not suitable for enantiomer separation and conglomerate crystal formation. .

期刊介绍:
Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. .
