Figure 4
(a) OD layer A1 of Mg(H2O)2[TeO2(OH)4] and (b) superposition of four A1 layers in the family structure. Te, Mg and O atoms are represented by yellow, blue and red spheres of arbitrary radius. The O1 and O2 atoms above Te and Mg (with respect to [001]) are omitted for clarity. Disordered 1:1 Te:Mg positions are represented by gray spheres. In (b) the coordinates of the O3 atom have been idealized to fulfill the equation x + y = ½. |
