This article is cited by 66 publications. Thus, the nanoclusters A, A1, and A2 can be considered as “determinants” of the corresponding structures. The nanocluster A was found only in two Pearson classes: cF464 and hP238, while the nanoclusters A1 and A2 occur in β′-Mg 2Al 3 only. Using the TOPOS procedure of searching for finite fragments in infinite nets we found that nanocluster B is a typical fragment of intermetallic compounds: it exists in intermetallics belonging to 42 Pearson classes. The self-assembly scheme proves the similarity of β, β′-Mg 2Al 3 to other extremely complicated Samson’s phases, NaCd 2 and ZrZn 22 the spatial arrangement of the centers of nanoclusters in these structures as well as the topology of the corresponding network conform to the Laves phase MgCu 2. The self-assembly of the β, β′-Mg 2Al 3 crystal structures was considered within the hierarchical scheme: 0D primary polyhedral clusters (coordination polyhedra) → 0D two-shell primary nanoclusters A, A1, A2, or B → 0D supracluster-precursor AB 2 → 1D primary chain → 2D microlayer → 3D microframework. The nanocluster model interprets structural disordering in β-Mg 2Al 3: the disordered atoms form the inner shell of the nanocluster A, while the outer shells of all nanoclusters are preserved. Using the TOPOS program package that implements the method, we separated two types of two-shell primary nanoclusters A, A1, A2, and B consisting of 57−63 atoms that completely compose the structures of the polymorphs. A novel method for the computational description of intermetallics as an assembly of nanoclusters was improved and applied to extremely complicated crystal structures of β, β′-Mg 2Al 3 polymorphs.
