Figure 1
Arrangement of the LiO4, LiO3(H2O) and SO4 tetrahedra in the Li2SO4·H2O crystal structure viewed along the [100] crystallographic direction. The symmetry operation [−x, y + 1/2, −z] relates atoms with their symmetry equivalents, which are marked by stars. In addition, the direction of the twofold screw axis parallel to [010], the monoclinic basis vectors and the corresponding unit cell are shown. |
