Figure 4
(a) The mol­ecular structure of BDHFN, showing the atom-labelling scheme, with displacement ellipsoids for non-H atoms drawn at the 30% probability level at 293 K [symmetry code: (A) −x, y, −z + [{1\over 2}]]. (b) The contribution of C⋯C contacts in the 2D fingerprints of BDHFN, indicating ππ inter­action a. (c) The shape-index surface of BDHFN, identifying ππ stacking inter­action a (not marked as there is only one type of interaction). (d) 1D chains formed by ππ stacking inter­action a (shown with red dashed lines), viewed along the [501] direction. The upper one is illustrated by the simplified structure (centre of gravity).
