Abstract
A theoretical study of electron density, ρ(r), and the Laplacian (ab initio, DFT B3LYP/6-31G(d, p) basis set) has been carried out for nine molecules of azathiens with aryl substituents (Ar-N=S=N-Ar1) and for sixteen dimers corresponding to typical arrangements of neighboring molecules in the crystal structures of Ar-N=S=N-Ar1. A dependence was established of the values of the electron density at (3, −1) critical points in the area of inter-stack and intra-stack atom-atom contacts on the internuclear distance.
