The Role of Hydrogen Bonds in Interactions between [PdCl4]2− Dianions in Crystal

open access: yesMolecules, 2022
[PdCl4]2− dianions are oriented within a crystal in such a way that a Cl of one unit approaches the Pd of another from directly above. Quantum calculations find this interaction to be highly repulsive with a large positive interaction energy.

Charge density view on bicalutamide molecular interactions in the monoclinic polymorph and androgen receptor binding pocket

open access: yesIUCrJ, 2020
High-resolution single-crystal X-ray measurements of the monoclinic polymorph of bicalutamide and the aspherical atom databank approach have served as a basis for a reconstruction of the charge density distribution of the drug and its androgen receptor ...

Halogen Bonds Formed between Substituted Imidazoliums and N Bases of Varying N-Hybridization

open access: yesMolecules, 2017
Heterodimers are constructed containing imidazolium and its halogen-substituted derivatives as Lewis acid. N in its sp3, sp2 and sp hybridizations is taken as the electron-donating base.

On the electrostatic potential profile in biased molecular wires

open access: yesThe Journal of Chemical Physics, 2002
The potential profile across a biased molecular junction is calculated within the framework of a simple Thomas–Fermi-type screening model. In particular, the relationship between this profile and the lateral molecular cross section is examined. We find that a transition from a linear potential profile to a potential that drops mainly near the molecule ...

Electrostatic potential profiles of molecular conductors [PDF]

open access: yesPhysical Review B, 2004
The electrostatic potential across a short ballistic molecular conductor depends sensitively on the geometry of its environment, and can affect its conduction significantly by influencing its energy levels and wave functions. We illustrate some of the issues involved by evaluating the potential profiles for a conducting gold wire and an aromatic phenyl

Electrostatic complementarity at the interface drives transient protein-protein interactions

open access: yesScientific Reports, 2023
Understanding the mechanisms driving bio-molecules binding and determining the resulting complexes’ stability is fundamental for the prediction of binding regions, which is the starting point for drug-ability and design.
