4-Chloro-3-(2,3,5-tri­methyl­phenoxy)­phthalo­nitrile

The asymmetric unit of the title compound, C₁₇H₁₃ClN₂O, contains two independent mol­ecules with no significant difference in their structures. The mol­ecules are non-planar. The dihedral angle between the two benzene rings is 79.20 (8)° in one mol­ecule and 79.54 (8)° in the other.

Propyl 4-(3,4-di­cyano­phenoxy)­benzoate

The title compound, C₁₈H₁₄N₂O₃, a phthalo­nitrile derivative, contains two aromatic rings, one of which carries two cyano groups. The crystal structure is stabilized by one intramol­ecular C—H...O and two intermolecular C—H...O hydrogen bonds.

4-(5-Indan­yl­oxy)phthalonitrile

Im the title compound, C₁₇H₁₂N₂O, the aromatic rings are twisted by 62.84 (4)° with respect to each other. There are no unusually short contacts between the mol­ecules and the crystal packing is controlled by weak van der Waals inter­actions.

(E)-2-[(2-Morpholinoethyl­imino)meth­yl]phenol

The title compound, C₁₃H₁₈N₂O₂, exists in the enol–imine tautomeric form with a strong intra­molecular O—H...N hydrogen bond [O...N = 2.5795 (18) Å], and the morpholine ring adopts an almost perfect chair conformation.
