[1-(1H-Imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol-κ2N7,N8]diiodidomercury(II)

In the title compound, [HgI2(C23H14N4O)], the HgII atom is four-coordinated by two N atoms from one 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol ligand and by two I atoms in a distorted tetrahedral environment. An intramolecular O—H...N hydrogen bond stabilizes the molecular conformation and an intermolecular N—H...I interaction stabilizes the crystal packing
