چکیده
In the title centrosymmetric compound, C(28)H(32)N(4)O(2) (2+) 2I(-), the two midazole rings are approximately perpendicular to the central anthracene ring system [dihedral angle = 86.6 (2)°]. The ionic units are linked into a two-dimensional network parallel to (01) by C-H⋯I hydrogen bonds and π-π inter-actions involving the anthracene ring system and imidazole rings [centroid-centroid distance = 3.717 (3) Å].
