Molecules 2022; 27:molecules27092885. [PMID: 35566234 PMCID: PMC9101229 DOI: 10.3390/molecules27092885] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 04/28/2022] [Accepted: 04/29/2022] [Indexed: 01/25/2023] Open
Abstract
The spodium–π bonding between MX2 (M = Zn, Cd, and Hg; X = Cl, Br, and I) acting as a Lewis acid, and C2H2/C2H4 acting as a Lewis base was studied by ab initio calculations. Two types of structures of cross (T) and parallel (P) forms are obtained. For the T form, the X–M–X axis adopts a cross configuration with the molecular axis of C≡C or C=C, but both of them are parallel in the P form. NCI, AIM, and electron density shifts analyses further, indicating that the spodium–π bonding exists in the binary complexes. Spodium–π bonding exhibits a partially covalent nature characterized with a negative energy density and large interaction energy. With the increase of electronegativity of the substituents on the Lewis acid or its decrease in the Lewis base, the interaction energies increase and vice versa. The spodium–π interaction is dominated by electrostatic interaction in most complexes, whereas dispersion and electrostatic energies are responsible for the stability of the MX2⋯C2F2 complexes. The spodium–π bonding further complements the concept of the spodium bond and provides a wider range of research on the adjustment of the strength of spodium bond.

Abstract
Abstract
Cyclic voltammetry, 1H nuclear magnetic resonance and quantum chemistry calculations were applied to explore the hydrogen bond interactions between ascorbic acid (AA) and glycine. The experimental results demonstrate the existence of hydrogen bonds in AA-glycine system, which has a significant effect on the oxidation peak potentials and currents of AA and the chemical shifts of glycine. The formation of hydrogen bonds between AA and glycine were further confirmed by the density functional theory, quantum theory of atoms in molecules and natural bond orbital analyses.

Abstract
Explosives are quite toxic and destructive; therefore, it is necessary to not only detect them but also remove them. The adsorption behavior of NX3 analytes (NCl3, NBr3 and NI3) over the microporous C2N surface was evaluated by DFT calculations. The nature of interactions between NX3 and C2N was characterized by adsorption energy, NCI, QTAIM, SAPT0, NBO, EDD and FMO analysis. The interaction energies of NX3 with C2N are in the range of −10.85 to −16.31 kcal mol−1 and follow the order of NCl3@C2N > NBr3@C2N > NI3@C2N, respectively. The 3D isosurfaces and 2D-RGD graph of NCI analysis qualitatively confirmed the existence of halogen bonding interactions among the studied systems. Halogen bonding was quantified by SAPT0 component energy analysis. The SAPT0 results revealed that ΔEdisp (56.75%) is the dominant contributor towards interaction energy, whereas contributions from ΔEelst and ΔEind are 29.41% and 14.34%, respectively. The QTAIM analysis also confirmed the presence of halogen bonding between atoms of NX3 and C2N surface. EDD analysis also validated NCI, QTAIM and NBO analysis. FMO analysis revealed that the adsorption of NI3 on the C2N surface caused the highest change in the EHOMO–LUMO gap (from 5.71 to 4.15 eV), and resulted in high sensitivity and selectivity of the C2N surface towards NI3, as compared to other analytes. It is worth mentioning that in all complexes, a significant difference in the EHOMO–LUMO gap was seen when electronic transitions occurred from the analyte to the C2N surface. Explosives are quite toxic and destructive; therefore, it is necessary to not only detect them but also remove them.![]()

Abstract
The complexes of B3O3H3 with acetylene and its substituted derivatives C2HX (X=H, F, Cl, Br, CH3, NH2) are explored by theoretical calculations using MP2 and M06-2X methods with aug-cc-pVDZ as the basis set. The different molecular electrostatic potential features of B3O3H3 with benzene (C6H6) and borazine (B3N3H6) result in different stable structures of the complexes with C2HX. The geometric analysis indicates that the global minimum is the parallel stacked (PS) structure with the linear C-C triple bond lies on the top of B3O3H3, and this is much different from that of the B3N3H6...C2HX complex, in which the C-H bond directs towards the B3N3H6 ring (T-shaped). The H-bonded structure where the C-H interacts with the O atom of B3O3H3 is found to be a local minimum. Besides, there is an additional X…O halogen-bonded structures for the B3O3H3…C2HX (X=Cl, Br) complexes. As for the PS geometry, when one H atom in C2H2 is replaced by different X groups, the binding energies of the complexes increases in the order of F<H<Cl<Br<CH3<NH2, which is mainly determined by the strength of the π-hole bond. The nature of interaction in these complexes is further studied by the atoms-in-molecules (AIM) and noncovalent interaction (NCI) analysis. The natural bond orbital (NBO) analysis indicates that the main orbital interaction arises from LPX→BD*B‑O for B3O3H3…C2HX (X=Cl, Br, NH2), and BDC‑C→BD*B‑O for B3O3H3…C2HX (X=H, CH3) complexes.

Abstract
Quantum DFT calculations, corrected for long-range interactions, have been carried out on complex models formed between HF as a proton donor and 2-methylene-2H-indene derivatives as proton acceptors. Using various exocyclic X substitutions, mutual effects of the aromaticity and the strength of the resulting π-hydrogen bond (after its evaluation by AIM methodology) have been investigated. The results show that the aromaticity of 6-membered rings and the hydrogen bond strength increase upon increasing the electron-donating character of the X-substituents. Based on some aromaticity indices (HOMA, FLU, SA and NICS(1)zz), it has been shown that the formation of a π-hydrogen bond causes an increase of aromaticity of the 6-membered ring. Also, the strength of the resulting π-hydrogen bond (with an energy of about 4.0 to 7.0 kcal mol-1) depends on the aromaticity of the 6-membered ring and increases with an increase in the aromaticity. In addition, a linear relationship was found between the most negative value of the molecular electrostatic potential (Vmin) and the HOMA, which confirms that the Vmin in the region of the studied ring could be used as a new index to estimate the amount of aromaticity. The electronic properties of the complexes have also been evaluated by means of the molecular electrostatic potential (MEP), the atoms in molecules (AIM) and the natural bond orbital (NBO) analyses.
