Figure 2
Models of the different observed structure types within RSi2 and R2TSi3 compounds (unit cell outlined in black). The AlB2-like structures are depicted such that the view onto the two-dimensional R network is almost identical. The common structure pattern of the ordered AlB2-like structures (gray frame at right top) is highlighted with a light-gray frame and red Si/T bonds. The structure types Ce2CoSi3 and U2RuSi3 are almost identical. In contrast to the U2RuSi3 type, the Si atoms of the Ce2CoSi3 type are on the highly symmetric z = ½ position. This is highlighted by the blurred Si location along the c direction. The tetragonal structures (gray frame at center top) compose a 3D Si/T subnetwork with incomplete hexagons at the faces (highlighted in orange). The structures are connected according to their symmetry relations (dashed lines, if the transition is not minimal; labels comprise the lattice transformation). |
