What is C2 space group?

The space group C2/c can be considered as a combination of a C-centred lattice with space group P2/c (or alternatively space group P21/n). This approach can be extended to the other 3 rotation axes of the primitive space group, yielding a total of 4 screw axes per unit cell in the C-centred space group.

What is space group in group theory?

In mathematics, physics and chemistry, a space group is the symmetry group of a configuration in space, usually in three dimensions. In crystallography, space groups are also called the crystallographic or Fedorov groups, and represent a description of the symmetry of the crystal.

What are the space groups in crystallography called?

In crystallography, space groups are also called the crystallographic or Fedorov groups, and represent a description of the symmetry of the crystal. A definitive source regarding 3-dimensional space groups is the International Tables for Crystallography (Hahn (2002)).

What are the names of the space groups?

Monoclinic crystal system Number Point group Orbifold Short name Full name (s) 3 2 22 {displaystyle 22} P2 P 1 2 1 4 2 22 {displaystyle 22} P2 1 P 1 2 1 1 11 2/m 2 ∗ {displaystyle 2*} P2 1 /m P 1 2 1 /m 1 12 2/m 2 ∗ {displaystyle 2*} C2/m C 1 2/m 1

How are space groups studied in other dimensions?

Space groups are also studied in dimensions other than 3 where they are sometimes called Bieberbach groups, and are discrete cocompact groups of isometries of an oriented Euclidean space . In crystallography, space groups are also called the crystallographic or Fedorov groups, and represent a description of the symmetry of the crystal.
