   The cohesive energy is a measure of the strength of the forces that bind atoms together in the solid state and is descriptive in studying the phase stability. The cohesive energy[…]is defined as the total energy of the constituent atoms minus the total energy of the compound[…]The computed cohesive energies are 6.101 eV/atom, 4.774 eV/atom and 6.512 eV/atom for BaRh₂, BaPd₂ and BaPt₂, respectively.
