Figure 4 Packing diagram viewed down the c-axis showing π⋯π stacking interactions between the adjacent cations. The aromatic rings of minor-occupancy component are omitted for clarity. Symmetry codes: (v) 1–x, 1 − y, 1 − z; (vi) −x + 1, −y + 2, −z + 1; (vii) –x, −y + 2, −z + 1; (viii) x + 1, y − 1, z; (ix) x + 1, y, z. |
