2D-Diamond and 2D-Center Rectangular Lattice Comparison

  1. Mar 30, 2015 #1
    Hi All,

    Using (Mirror + Translation in 2D).
    I see that Diamond and Center Rectangular Lattice in 2D has the same Symmetry i.e:

    1)Horizontal Mirror Plane
    2)Vertical Mirror Plane
    3)2-Fold Rotation Axis.

    and Diamond has Smaller Area.

    Then why we say Center Rectangular has higher Symmetry and we take it as the Standard Cell.
