Descrição: The structures of stoichiometric compositions AB, A2B, and A3B for structures, B19, L10, L12, D019, D022, D023, D024, A15, C14, C15 and C36 have been investigated based on the analysis of diagrams in coordinates of space-filling coefficients Ψ on superstructural compression ΔΩ/Ω. On the basis of the analysis of the abovementioned diagrams, the equation Ψ = f0+f1(ΔΩ/Ω) has been obtained, and coefficients f0 and f1 of the equation for the investigated structures have been determined. It has been established that values of coefficients f0 and f1 for Laves phases have higher values than for all other compounds.
