Bilbao Crystallographic Server Point Groups Retrieval Tools Help Wyckoff positions of the two-dimensional crystallographic point groups

Wyckoff Positions of 2D Crystallographic Point Groups

This program permits the access to the information about the wyckof positions ofthe two-dimensional crystallographic point groups. One has to select one point group among the ten two-dimensional crystallograhic point groups in the following table:

1 2 m 2mm 4 4mm 3 3m1 31m 6 6mm

Once the point group is chosen the information about the Wyckoff position is shown:
