Figure 1
Coordination sphere around the Na+ cation. The Na+ cation makes a total of eight contacts (dashed lines) to three individual boron cluster anions and to one sulfur dioxide molecule. Displacement ellipsoids are drawn at the 50% probability level and hydrogen atoms are shown with arbitrary radii. Symmetry codes: (a) 1 + x, y, z; (b) −1 + x, − + y, − z. |
