{9-Hexyl-2-[2-phenyl-6-(pyridin-2-yl)pyridin-4-yl]-9H-carbazole}di­iodido­zinc

In the title compound, [ZnI₂(C₃₄H₃₁N₃)], the Zn^II atom is four-coordinated by two I atoms and the pyridine N atoms from the bidentate 6'-phenyl-2,2'-bi­pyridine ligand in a distorted tetra­hedral geometry.

3-(3-Methyl­phen­yl)-5-(quinolin-8-yl­meth­oxy)-1,2,4-oxa­diazole monohydrate

In the title compound, C₁₉H₁₅N₃O₂·H₂O, the oxa­diazole ring and the quinoline unit are almost coplanar, making a dihedral angle of 7.66 (8)°. The dihedral angle between the benzene ring and the quinoline system is 25.95 (8)° while that between the benzene and the oxa­diazole rings is 18.88 (9)°. The water mol­ecule is hydrogen bonded to an oxa­diazole N atom and to the quinoline N atom. In the crystal, these units are linked via C—H...O hydrogen bonds, forming two-dimensional net­works lying parallel to the ab plane.
