Bilbao Crystallographic Server Point Groups Retrieval Tools Help Wyckoff positions of the two-dimensional 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 |
Multiplicity | Letter | Site Symmetry | Coordinates |
8 | c | 1 | (x,y)(-x,-y)(-y,x)(y,-x)(-x,y)(x,-y)(y,x)(-y,-x) |
4 | b | ..m | (x,x)(-x,-x)(-x,x)(x,-x) |
4 | a | .m. | (x,0)(-x,0)(0,x)(0,-x) |
1 | o | 4mm | (0,0) |
