Figure 1 The structure of (I) including the asymmetric unit (labeled atoms) and anions completed through symmetry operators: unlabeled atoms in the C10 anion are related to labeled atoms by symmetry code −x + 1, −y, −z + 1; unlabeled atoms in the C16 anion are related to labeled atoms by symmetry code −x + 1, −y, −z. Displacement ellipsoids for non-H atoms are drawn at the 30% probability level. Hydrogen bonds are shown as dashed lines. |
