✦ Synopsis

In the title crystal structure, C~38~H~44~N~10~O~2~
^4+^·4ClO~4~
^−^·2H~2~O, components are linked into a two-dimensional framework by a combination of N—H...O, C—H...O, O—H...O and N—H...N hydrogen bonds. In addition, weak π–π stacking interactions and anion–π noncovalent interactions between perchlorate anions and heteroaromatic imidazole rings [O...Cg = 3.328 (10) and 3.386 (11) Å; Cg is the centroid of an imidazole ring] consolidate the crystal structure.
