Hence the number of atoms per unit cell 8 × (1/8) 1 only. Therefore, the contribution of each atom to the unit cell 1/8. Each atom is equally shared by eight atoms because each cube contains eight corners.

A rough estimate of the energy due to partial covalent bonding was made and is shown to be quite important for the stability. Formation of partial covalent bonds between molecules in this structure, but not in the cubic structure, may account for the stability of the former. Possible inappropriate ratio between the two coefficients in the Lennard-Jones potential does not seem to account for the observed stability of the orthorhombic structure. A similar situation was found for iodine. Thus, the cubic structure has a little lower energy than the orthorhombic structure. A Lennard-Jones type potential was assumed between nuclei of the interacting molecules. The lattice energy of the crystals of halogen molecules Cl 2 and I 2 is calculated for orthorhombic structure (space group Bmab ) and cubic structure (space group P a 3) by varying lattice parameters ( a, b, c, and the orientation angle, ϕ, of the molecular axes) and finding the minimum of the energy.
