New types of two-layer nanoclusters with an icosahedral core
New types of 63-atom two-layer nanoclusters based on the icosahedral core and having the maximum symmetry D 3d or T h in crystal have been found using the method of the nanocluster analysis (the TOPOS program package) in the database that was created of crystal structures of intermetallides containing 20319 compounds. It has been shown that these nanoclusters may participate in assembling the crystal and/or be present there as stable fundamental configurations of atoms. The possibilities of the method of the nanocluster analysis have been demonstrated by the example of calculating the chemical composition of the crystal presented as an ensemble of nanoclusters.
