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.
