Figure 3
Crystal structures of A2 + nTtnD series compounds. n = 1: Ti3SnD (Pm m) and Ti3 > SnDx (x < 1) (C2221); n = 2: Li4Ge2D and Li4Si2D (Cmmm); n = 3: Ti5Sn3D (P63/mcm). The large dark and small light spheres represent Tt and A, respectively, and the interstitial D atoms are centered in the shaded Li6 octahedra. |
