Figure 1
A view of the structure of the anion of (I[link]), showing the atomic numbering scheme. All H atoms have been omitted for clarity, and only one of the disordered positions for each of atoms C20 and C20′ is shown. Displacement ellipsoids are drawn at the 50% probability level for non-H atoms. [Symmetry code: (i) [-x,y,{3\over2}-z].]
