There exist a large number of well-characterized MT2X2 intermetallic compounds which form in two slightly different tetragonal crystal structures. For the purposes of this overview M is restricted to uranium or cerium, T denotes a transition metal (3d, 4d or 5d), and X is silicon or germanium. The crystal structures are shown in Fig. 1 and consist of the ThCr2Si2 and CaBe2Ge2 types. Note the symmetry change due to the different stacking sequences of T and X, while the U or Ce sites remain approximately fixed.
