In the mol-ecule of the title compound, [HgI(2)(C(24)H(16)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the bidentate 4,7-diphenyl-1,10-phenanthroline and two iodide ligands. There is a π-π contact between the pyridine and phenyl rings [centroid-to-centroid distance = 4.2387 (4) Å].

The asymmetric unit of the title compound is composed of one host mol-ecule, -4-(1 ,5 -3-aza-1,5(3,9)-dicarbazola-cyclo-octa-phane-3-yl)benzo-nitrile and one di-chloro-methane solvate mol-ecule, CHN·CHCl. The host mol-ecule possesses a planar chirality but crystallizes as a racemate in the space group 2/. It adopts an -configuration, in which two carbazole rings are partially overlapped with a parallel orientation.
