Figure 3
(a) The mol­ecular structure of BDHMFI, 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 + 2, −y, −z]. (b) The dimer structure formed by two BDHMFI mol­ecules and one disordered aceto­nitrile mol­ecule through hydrogen bonds a (two red spots on the dnorm Hirshfeld surface). (c) The shape-index surface of BDHMFI, identifying ππ stacking inter­action b. Only red and blue triangles on the surface are shown for clarity. (d) NCIs a and b (shown with red and green dashed lines, respectively) link BDHMFI mol­ecules into an infinite 1D chain extending roughly along the [10[\overline{3}]] direction, viewed along the [1, 9, [\overline{5}]] direction.
