Figure 2
Ball-and-stick models of the two crystallographically independent [SeO4]2− ions with atom numbering of the asymmetric unit and orientation of the threefold rotation axis (blue). With exception of the hydrogen atoms, which are shown as spheres of arbitrary radius, all other atoms are drawn as displacement ellipsoids at the 40% level. Coordination bonds between oxygen and barium are drawn as shortened, two-colored sticks, hydrogen bonds between oxygen and hydrogen atoms of water molecules and hydroxyl groups are drawn as dashed lines (red). |
