Figure 2
The mol­ecular structures of the (a) first and (b) second independent anions in (I)[link], showing the atom-labelling scheme and displacement ellipsoids at the 50% probability level. (c) An overlap diagram highlighting the differences in the conformations of the first (red) and second (blue) independent anions. The anions are overlapped so the α-atoms about the chiral centre are coincident.
