Figure 5 A molecular diagram showing the atom-numbering scheme for the anions in (II). Displacement ellipsoids are drawn at the 50% probability level. The minor-component disordered Br atoms (see Comment) have been omitted for clarity. [Symmetry codes: (iii) −x + 1, −y + 1, −z + 2; (iv) −x, −y + 1, −z + 1.]
