The silicon rich rare earth compounds with the formula RSi2-x crystallise in three different structure types (as shown in Figure 967): The orthorhombic GdSi2-type structure is a deformation of the tetragonal ThSi2 type even though their relation with the hexagonal AlB2 type structure is not straightforward. These plates in Figure 967 are stacked along the [001] direction in the tetragonal and orthorhombic structures and along the [1010] direction in the hexagonal one. [1]
