Abstract
Single-crystal X-ray diffraction and quantum mechanical theories were used to examine in detail the subtle nature of non-covalent interactions in the [2:1:1] multicomponent crystal of 1,1-aminocyclopentanecarboxylic acid:oxalic acid:water. The crystal, which is a hydrate salt of the amino acid with the hydrogen-oxalate ion, also contains the zwitterion of the amino acid in equal proportions. It was found that a dimeric cation [Acc5(Z)...Acc5(C)]+ bonded by an O-H...O hydrogen bond exists due to a charge transfer between acid and carboxylate groups. The three-dimensional crystal is built by blocks stacked along the [101] direction by dispersion interactions, with each block growing along two directions: a hydrogen oxalate HOX-...HOX- catameric supramolecular structure along the [010] direction; and double ...HOX--W-[Acc5(Z)... Acc5(C)]+... chains related by inversion centers along the [1 0 {\bar 1}] direction. A PBE-DFT optimization, under periodic boundary conditions, was carried out. The fully optimized structure obtained was used to extract the coordinates to calculate the stabilization energy between the dimers under the crystal field, employing the M062X/aug-cc-pVTZ level of theory. The non-covalent index isosurfaces employed here allow the visualization of where the hydrogen bond and dispersion interactions contribute within the crystal. The crystal atomic arrangements are analyzed by employing the Atoms in Molecules and electron localization function theories. Within this context, the presence of density bond critical points is employed as a criterion for proving the existence of the hydrogen bond and it was found that these results agree with those rendered by the crystallographic geometrical analysis, with only three exceptions, for which bond critical points were not found.

Abstract
The new release of the computer program packageWinXPRO v.3xfor determination of the crystal properties from parameters of the multipole-modeled experimental electron density and anharmonic atomic displacement coefficients is described. The set of properties is significantly extended by using the density functional and information theories. In addition, a built-in multi-functional viewer and programs to display the output data, including the mapping of the chosen functional bonding descriptors onto surfaces of the other properties, are included.

Abstract
Emissions of greenhouse gases due to human activities have been well documented as well as the effects on global warming resulting from it. Efforts to reduce greenhouse gases at the source are crucial to curb climate change, but due to insignificant economic incentives to reduce usage of fossil fuels, not a lot of progress has been made by this route. This necessitates additional measures to reduce the occurrence of greenhouse gases in the atmosphere. Here we used theoretical methods to study the solubility of carbon dioxide in ionic liquids (ILs) since sequestration of CO2 in ILs has been proposed as a possible technology for reducing the emissions of CO2 to the atmosphere. Ionic liquids form a class of solvents with melting temperatures below 100 °C and, due to very low vapor pressures, which are not volatile. We have performed molecular dynamics (MD) simulations of 1-ethyl-3-methylimidazolium (C2mim) bis(trifluoromethylsulfonyl)imide (Tf2N) and its mixtures with carbon dioxide in order to investigate the CO2 concentration effect on the CO2-cation and CO2-anion interactions. A systematic investigation of CO2 concentration effects on resulting equilibrium liquid structure, and the local environment of the ions is provided. The Quantum Theory of Atoms in Molecules (QTAIM) was used to determine the interaction energy for CO2-cation and CO2-anion complexes from uncorrelated structures derived from MD simulations. A spatial distribution function analysis demonstrates the specific interactions between CO2 and the ionic liquid. Our findings indicate that the total volume of the system increases with the CO2 concentration, with a molar volume of CO2 of about 0.038 L/mol, corresponding to liquid CO2 under a pressure of 100 bar. In other words, the IL effectively pressurizes the CO2 inside its matrix. The thermodynamics of CO2 solvation in C2 min-Tf2N were computed using free energy techniques, and the solubility of CO2 is found to be higher in this IL (-3.7 ± 1 kcal/mol) than in water (+0.2 kJ/mol), predominantly due to anion-CO2 interactions.
