(a) The molecular structure of BMHFI, 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 BMHFI, mapped over dnorm. Three red spots correspond to N3—H24⋯O1(x + , −y + , −z) (marked a) and C3—H3⋯O1(x + 1, y, z) (marked b) interactions. (c) 1D chains formed by NCIs a and b (shown with green and red dashed lines, respectively), viewed perpendicular to the extending direction, i.e. the a axis. The upper two lines are illustrated by the simplified structure (centre of gravity). (d) 1D chains formed by the aforementioned NCIs a and b, viewed along the extending direction, i.e. the a axis, aiming to show the packing mode of four different orientations (simplified structure with four different colours). |
