Venkatesan, Perumal;Thamotharan, Subbiah;Percino, M. Judith;Ilangovan, Andivelu research published 《 Crystal Packing Modulation of the Strength of Resonance-Assisted Hydrogen Bonds and the Role of Resonance-Assisted Pseudoring Stacking in Geminal Amido Esters: Study Based on Crystallography and Theoretical Calculations》, the research content is summarized as follows. A detailed exptl. and theor. study of substituted geminal amido esters (Et (2E)-3-(arylamino)-2-(arylcarbamoyl)prop-2-enoate, AME-1-8) leading to the identification of a unique angularly fused pseudotricyclic (S(6),S(6),S(6)) ring system stabilized by an intramol. resonance-assisted H bond (RAHB) and a non-RAHB are presented in addition to weak intermol. interactions. An anal. of x-ray and theor. models reveals that the strength of the intramol. RAHB (N1-H1_N···O1) varies in a wide range (6.9-11.4 kcal mol^-1) due to crystal-packing constraints arising from different aromatic ring substitutions. The effect is less significant and the strength differs only in a narrow range (8.2-9.9 kcal mol^-1) in the case of non-RAHB. The downfield shift (δ ≈ 12.3) observed for the N-H_aniline signal in ¹H NMR spectra of AME-1-8 is due to the presence of intramol. RAHB. A PIXEL energy anal. suggests that the mol. dimer formed by stacking of RAHB pseudorings is strong (E_tot = -14.4 to -17.9 kcal mol^-1), and this dimer forms the basic motif in most of the reported structures. A detailed anal. of the isostructurality suggests that the basic motif exists in most of the structural combinations. The weak intermol. C-H···O, C-H···Cl, and C-H···π interactions play a vital role in the stabilization of these crystal structures, as evaluated by PIXEL and Bader′s quantum theory of atoms in mols. approach (QTAIM). A lattice energy anal. suggests that the Coulombic contribution and total lattice energies are higher in the para-substituted compounds (AME-2, AME-5, and AME-8) in comparison to the other isomeric compounds The crystal packing of these compounds is analyzed from the energy frameworks. Most of the crystals show similar 3D topols., suggesting that these compounds may have similar mech. behavior.

Judith;Ilangovan, Andivelu research published 《 Intramolecular resonance assisted N-H···O=C hydrogen bond and weak noncovalent interactions in two asymmetrically substituted geminal amido-esters: Crystal structures and quantum chemical exploration》, the research content is summarized as follows. Two asym. substituted geminal amido-esters, namely Et (2E)-2-[(2,5-dimethoxy phenyl)carbamoyl]-3-[(4-nitrophenyl)amino] prop-2-enoate (I) and Et (2E)-2-[(9,10-dioxo-9,10-dihydroanthracen-1-yl)carbamoyl]-3-(phenylamino) prop-2-enoate (II) were synthesized and the nature and strength of intramol. resonance assisted hydrogen bond (RAHB) and non-RAHB was studied. X-ray anal. revealed that intramol. N-H···O, and C-H···O interactions lead to the formation of angularly fused pseudo tricyclic (A-C) motif in compound I and fused pseudo pentacyclic (A-E) motif in compound II. Intramol. RAHB; non-RAHB interactions are characterized and quantified by Bader’s quantum theory of atoms-in-mols. approach (QTAIM). In both compounds, ring A was found to exhibit intramol. RAHB characteristics. Crystal structures of I and II are stabilized by weak intermol. C-H···O, C-H···π, and π···π interactions. Intermol. interaction energies for different mol. dimers in I and II have been quantified by using the PIXEL, QTAIM, and DFT methods. The pseudoring stacking interaction is observed only in compound II whereas no such stacking interactions are seen in compound I. Hirshfeld surface (HS) anal. suggested that the H···H and O···H contacts are the first and second dominant contacts in both crystal structures. The theor. charge d. anal. revealed that the C-H···O and C-H···C(π) interactions produce closed-shell characteristics. Further, the crystal packing of compounds I and II analyzed based on the energy frameworks.
