DFT-PBE, DFT-D, and MP2 Studies on the H2O•••HNH and HOH•••NH2 Hydrogen Bonds in Water-Aniline Complexes

DFT-GGA method of Perdew-Burke-Ernzerhof (PBE) is used with aug-cc-PVTZ, 6-311++G**, and Def2-TZVP large basis sets to study the hydrogen bond interactions between oxygen lone pair as a donor electron with hydrogen atom connected to the aniline’s nitrogen as an electron acceptor (H2O···HNH-Ph), and nitrogen lone pair with hydrogen of water molecule (Ph-H2N···HOH...

Water's non-tetrahedral side.

The case for liquid water having non-tetrahedral as well as tetrahedral coordination is put forward. Given the dependence of structure on the hydrogen bond definition, a recent conceptual breakthrough has been the topological hydrogen bond definition which overcomes the shortcomings of traditional cut-off-based hydrogen bond definitions. It identifies the hydrogen bonds in water's first coordin...

Liquid water: from symmetry distortions to diffusive motion.

Water deviates from tetrahedral symmetry on different scales, creating "defects" that are important for its dynamics. In this Account, I trace the manifestations of these distortions from the isolated molecule through gas-phase clusters to the liquid phase. Unlike the common depiction, an isolated water molecule has a nonsymmetric charge distribution: although its positive charge is localized a...

Role of Hydrogen Transfer and Ionic Bonding on RR, SS and RS Medetomidine Conglomerates/Acids Stability: A Theoretical Study

This study focuses on RR, SS and RS medetomidine (MM) and inclusion of several achiral acids to distinguish which acid can help conglomerate formation instead of crystallizating racemic mixtures by defining the low-lying energy of their structures. Favorable orientation of acids was determined in interaction with the MM enantiomers after optimization. The most noticeable interactions include hy...

Inductive Effect of Bioactive Intermolecular Hydrogen Bonding Complex of 1,2,4,5 –Tetrazine and Inorganic Acid by NMR and QTAIM

In this paper, NMR and QTAIM analysis for three substituted of T2SA complex was investigated in the gas and four solvents at DFT level. Intermolecular O–H…N hydrogen bonds between 1,2,4,5-Tetrazine and Sulphurous acids enhance the stability of complex.1,2,4,5-Tetrazine is a highly reactive diene for [4+2] inverse-Diels–Alder cycloaddition processes and an excellent precursor to attain the pyrid...
