Figure 1
Polyhedral plot of magnesiotaaffeite-2N′2S2 viewed down [010] with cation site nomenclature and coordination numbers given to the right. Module sequence is N′–S–S–N′′–N′ from bottom to top, with boundaries indicated by horizontal lines. Displacement ellipsoids are drawn at the 99% probability level. Mg atoms are shown in yellow, Al in blue, Be in green and O in red. |
