Figure 3
Sections of the crystal structure of Pd6.69Sn4.31, with a) layers `B1'–`Al1'–`B6' and b) layers `B2'–`Al2'–`B1'. The voids are drawn as empty squares and are connected to the neighbouring Sn atoms by dashed lines. Shown are the surroundings of the `B' layer atoms with zero (Sn1), one (Pd4) and two voids (Pd1, Pd2, Pd3, Pd5). Anisotropic displacement ellipsoids are drawn at the 90% probability level. |
