Figure 2
The kröhnkite-type chain in the crystal structure of (NH4)Mg(HSO4)(SO4)(H2O)2 at 100 K. [MgO4(OH2)2] octahedra are blue, SO3(OH) tetrahedra are orange and SO4 tetrahedra are red. Displacement ellipsoids are drawn at the 74% probability level and H atoms are given as grey spheres of arbitrary radius. [Symmetry codes: (i) −x, −y + 1, −z + 1; (ii) −x + 1, −y, −z + 1.] |
