Figure 7
(a) The molecular structure of BMHMFI, showing the atom-labelling scheme, with displacement ellipsoids for non-H atoms drawn at the 30% probability level at 293 K. (b) The Hirshfeld surface for BMHMFI, mapped over dnorm. The intermolecular hydrogen bonds a calculated using PLATON, but another kind of hydrogen bond [C11—H11⋯N1(x, −y − , z − ), which can be found as red spots] was not suggested by PLATON. (c) The shape-index surface of BMHMFI, identifying π–π stacking interactions b and c. (d) 1D chains formed by C—H⋯π interactions a (shown with red dashed lines) can be woven into a 2D layer structure by π–π interactions b and c (shown with green and blue dashed lines, respectively), viewed along the a axis. |
