Abstract

The polytypic structures of Pd₈T₃ (T = As, Sb) compounds was revealed using the graph method. The topology of the layers and the pattern in the sequence of their alternation are analyzed. The ordering of antimony and arsenic atoms by positions at the nodes of layer-networks and the positional disorder in the sequence of alternating layers, which lead to the formation of different structural polytypes, are considered.

Keywords

graphs, nets, close packing, order-disorder, positional disorder, polytypes, palladium compounds
