Every pair of atoms can be bonded together showing a variety of different bonding regimes, the internuclear distance being the controlling parameter that decides under which chemical pattern a given pair will act. The type of bond that best describes a given compound is thus a consequence of the equilibrium distances on its main atomic pairs. Therefore, we should act cautiously in extrapolating the typical molecular regime to material science, particularly when high pressures or far from room temperatures are involved.
