X-Ray Spectral and Theoretical Study of Electronic Structure and Features of Interatomic Interactions in Phenylaminosilanes HnSi(NHC6H5)4–n (n = 3–0)

Abstract

Electronic structure and features of interatomic interactions in a series of phenylaminosilanes H_nSi(NHC₆H₅)_4–n (n = 3–0) have been studied by means of computer-based simulation (electron density functional method) in comparison with experimental (X-ray and photoelectron spectroscopy). Distributions of density of electronic states of the valence band, correlation diagrams of the energy levels, and visualizations of the isosurfaces of molecular orbitals have been obtained. Major types of interatomic electronic interactions providing the Si–NH–C₆H₅ bonds in tetraphenylaminosilane have been elucidated.
