چکیده
The mol-ecule of the title compound, C(23)H(17)NO(2), a Schiff base derived from 2-hydr-oxy-1-naphthaldehyde, crystallizes in the keto-amine tautomeric form. The dihedral angle between the aniline and hydroxy-benzene rings is 77.41 (17)°, whereas the planes of the naphthaldehyde and fused aniline benzene rings are nearly coplanar, making a dihedral angle of 8.29 (15)°. Intra-molecular N-H⋯O hydrogen bonding, a characteristic hydrogen bond for Schiff bases, helps to stabilize the mol-ecular structure. Weak inter-molecular C-H⋯π inter-actions are present in the crystal structure.

In the title compound, [HgI(2)(C(23)H(14)N(4)O)], the Hg(II) 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 tetra-hedral environment. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation and an inter-molecular N-H⋯I inter-action stabilizes the crystal packing.
