3-(2-Nitro­phen­oxy)phthalonitrile

In the title compound, C14H7N3O3, the dihedral angle between the two arene units is 62.57 (12)°

4-[2-(Cyclo­hexa-1,4-dien-1-yl)eth­oxy]benzene-1,2-dicarbonitrile

In the title compound, C16H14N2O, the dihedral angle between the aromatic rings is 70.23 (6)°. The linking chain has a zigzag conformation. In the crystal, mol­ecules are linked by weak inter­molecular C—H⋯N hydrogen bonds, forming a zigzag chain along the c axis

Crystal Structure Of 4-(3,4-Di­Cyano­Phen­Oxy)-N-[3-(Di­Methyl­Amino)­Prop­Yl]Benzamide Mono­Hydrate: A Phen­Oxy­Phthalo­Nitrile Derivative

In the title compound, the planes of the phen­oxy and phthalo­nitrile rings are oriented at a dihedral angle of 60.39 (5)°. In the crystal, mol­ecules are linked by O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds, forming slabs parallel to (100). The slabs are linked by a pair of inversion-related C—H⋯N hydrogen bonds, forming a three-dimensional structure., In the title compound, C20H20N4O2·H2O, the planes of the phen­oxy and phthalo­nitrile rings are oriented at a dihedral angle of 60.39 (5)°. The 3-(di­­methyl­amino)­propyl chain has an extended conformation and is cis with respect to the phthalo­nitrile ring. In the crystal, O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds link the mol­ecules to form slabs parallel to (100). There are also C—H⋯O and C—H⋯N hydrogen bonds and C—H⋯π inter­actions present within the slabs. The slabs are linked by a pair of inversion-related C—H⋯N hydrogen bonds, involving phthalo­nitrile rings, forming a three-dimensional structure.PubMedScopu
