Figure 1
Asymmetric unit of [(NH4)1–x(H3O)x]2[Yb6F8(O2CCF3)12(H2O)4]·4H2O (x = 1/4), as related to the NH4+-containing partial occupation site (a) and as related to the H3O+-containing partial occupation site (b), shown separately with the same view direction and the same scaling. Displacement ellipsoids are drawn at the 50% probability level, hydrogen atoms are drawn with an arbitrary radius. The CF3 groups at C5 and C11 suffer from rotational disorder that is not related to the cation substitution; only F atoms of the major occupied sites are shown. The directions of further Yb—O and Yb—F bonds are given by truncated sticks, the directions of hydrogen-bonding by segmented blue sticks. Note the coincidence of most parts of the partial occupation site models and the significant differences in the cation/water region and the coordination spheres of Yb2 and Yb3. |
