Interactions between nitrate ions and their effect on charge redistribution in pentaerythrityltetraammonium tetranitrate crystal
Based on a detailed study of the electron density distribution function in pentaerythrityltetraammonium tetranitrate, reconstructed from high resolution X-ray diffraction data, the effect of unusual (from the standpoint of electrostatic considerations) anion-anion contacts on the charge distribution in the crystal was analyzed. Interactions between the likely charged species can cause a significant redistribution of the charge density over the anionic (cationic) sublattice and, as a result, significantly affect the strength of conventional cation-anion bonds.
