Figure 1
The asymmetric unit of (I), showing the four independent molecules (labelled A–D), with displacement ellipsoids drawn at the 40% probability level. Unlabelled atoms follow the same label sequence as molecule A. π–π bonds are represented by dashed lines connecting ring centres and Br⋯Br interactions are represented by double-dashed lines. [Symmetry codes: (i) −x + 1, −y + 2, −z + 1; (ii) −x, −y + 1, −z + 1; (iii) −x, −y, −z; (iv) −x + 1, −y + 1, −z; (v) −x + 1, −y + 1, −z + 1; (vi) −x, −y + 1, −z.] |
