(a) The mol­ecular structure of BMHAI, 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 Hirshfeld surface for BMHAI, mapped over dnorm. Three kinds of inter­molecular hydrogen bonds and one kind of intra­molecular hydrogen bond can be visualized as red spots, but only hydrogen bond a was confirmed by the PLATON program (Spek, 2009BB102). (c) 1D chains along the a and b axes formed by the aforementioned hydrogen bonds a (shown with red dashed lines), viewed along the a axis, aiming to show the packing mode of the eight different orientations as a simplified structure with eight different colours, i.e. orange, red, green, blue, purple, violet, yellow and indigo.
