Figure 1
The principal building units, LaO9 polyhedra and SO4 tetrahedra, in the crystal structure of (NH4)[La(SO4)2(H2O)], showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level. [Symmetry codes: (i) 1 − x, − + y, − z; (ii) 1 − x, + y, − z; (iii) 1 − x, 2 − y, −z; (iv) 2 − x, 2 − y, 1 − z; (v) x, − y, + z.] |
