Validation of Chemical Bonding by Charge‑Density Descriptors: The Current Scenario

Abstract

Electron-density distribution influences the chemical and
physical properties of a material. Modern experimental and theoretical
charge-density methods have become reliable in determining the nature
of chemical bonding. Latest developments in the field of X-ray sources,
detector technologies, and new analytical descriptors have helped it
evolve over the years as a dynamic area of advanced crystallography.
This review provides a short introduction to charge-density methods and
highlights recent experimental results to understand the chemical concepts
and material properties better. Potential applications of chargedensity
analysis and possible directions are discussed.
