Energy aspect of the chemical bonding peculiarities in the crystal of sodium iodide dihydrate

Abstract

Chemical bonding peculiarities in the crystalline dihydrate of sodium iodide were examined by means of Bader's “Atoms in Molecule” theory and the energies of cation–anion, cation–water and anion–water contacts were estimated on the basis of the experimental data that were shown to provide insight into the tendency of NaI to form co-crystals with the majority of solvents.
