1-{(Z)-1-(2,4-Dichloro­phen­yl)-1-[2-(4-methyl­phen­oxy)eth­oxy]prop-1-en-2-yl}-1H-imidazol-3-ium nitrate

In the title salt, C₂₁H₂₁Cl₂N₂O₂⁺·NO₃⁻, the imidazole ring makes dihedral angles of 43.39 (14) and 10.9 (2)° with the 4-methyl­phenyl and 2,4-dichloro­phenyl rings, respectively. The mol­ecule adopts a Z conformation about the C=C double bond, which links the imidazole ring to the 4-methyl­phen­oxy unit via an eth­oxy chain. In the crystal, cations and anions are linked into chains by N—H...O and C—H...O hydrogen bonds.

2-(4-Methyl­phen­yl)-3-oxo-4-phenyl-2,3,3a,4,9,9a-hexa­hydro-1H-benzo[f]iso­indole-6-carbo­nitrile

In the title compound, C₂₆H₂₂N₂O, one phenyl ring, one five-membered N-heterocyclic ring and one six-membered carbocyclic ring make up the hexa­hydro­benzo[f]iso­indole core. Another phenyl group is attached to the heterocyclic N atom as a substituent. The non-aromatic five- and six-membered rings both exhibit boat conformations. In the crystal, weak C—H...O and C—H...N inter­actions establish the observed three-dimensional structure. The crystal studied was refined as an inversion twin.
