 Monoclinic
Laue class

Asymm
 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1/4 and 0 ≤ z ≤1
Number of symmetry operators
 4 Crystal symmetry Is non-centrosymmetric because it has not -x,-y,-z in its symmetry (no center of inversion).
Symmetry (atomic coordinates)
X, Y, Z; X, -Y, 1/2+Z; 1/2+X, 1/2+Y, Z; 1/2+X, 1/2-Y, 1/2+Z
Crystal examples
  

For a monoclinic crystal system, if the systematic absences show the presence of C-center and c-glide, then the possible space group can be Cc.
