The asymmetric unit of the title compound, C22H25F2N4O2, contains two crystallographically independent molecules. In one molecule, the two benzene rings are oriented at a dihedral angle of 1.93 (10)° and in the other molecule the corresponding dihedral angle is 7.19 (9)°. The piperidine rings in the two molecules adopt a similar distorted chair conformation, and both have pseudo-mirror planes passing through the N—O bonds. An intramolecular O—H...N hydrogen bond between the hydroxy group and the imine N atom is observed in both molecules. In the crystal, weak C—H...O and C—H...F hydrogen bonds, enclosingR22(6) ring motifs, and weak π–π stacking interactions link the molecules into a three-dimensional supramolecular network, with centroid-to-centroid distances between the nearly parallel phenyl and benzene rings of adjacent molecules of 3.975 (2) and 3.782 (2) Å.

Dimethylformamide Solution

The title compound, C22H17NO2·C3H7NO, was synthesized by condensation of an aromatic aldehyde with a secondary amine and subsequent reduction. It was crystallized from a dimethylformamide solution as a monosolvate, C22H17NO2·C3H7NO. The aromatic molecule is non-planar with a dihedral angle between the mean planes of the aniline moiety and the methyl anthracene moiety of 81.36 (8)°. The torsion angle of the Caryl—CH2—NH—Caryl backbone is 175.9 (2)°. The crystal structure exhibits a three-dimensional supramolecular network, resulting from hydrogen-bonding interactions between the carboxylic OH group and the solvent O atom as well as between the amine functionality and the O atom of the carboxylic group and additional C—H...π interactions. Hirshfeld surface analysis was performed to quantify the intermolecular interactions.

Tetrahedral Anion

The structure of the title salt, (C8H10NO)2[CoCl4], is isotypic with the analogous cuprate(II) structure. The asymmetric unit contains one 4-acetylanilinium cation and one half of a tetrachloridocobaltate(II) anion for which the CoIIatom and two Cl−ligands lie on a mirror plane. The Co—Cl distances in the distorted tetrahedral anion range from 2.2519 (6) to 2.2954 (9) Å and the Cl—Co—Cl angles range from 106.53 (2) to 110.81 (4)°. In the crystal, cations are self-assembled by intermolecular N—H...O hydrogen-bonding interactions, leading to aC(8) chain motif with the chains running parallel to thebaxis. π–π stacking interactions between benzene rings, with a centroid-to-centroid distance of 3.709 Å, are also observed along this direction. The CoCl42−anions are sandwiched between the cationic chains and interact with each other through intermolecular N—H...Cl hydrogen-bonding interactions, forming a three-dimensional network structure.

In the asymmetric unit of the title compound, C13H13N3O3, the 2-(2-methoxphenyl)ethenyl unit is connected to the methyl-nitroimidazole 1-methyl-4-nitro-1H-imidazole moiety. The molecule is quasi-planar and the planes of the two rings form a dihedral angle of 0.92 (11)°. The crystal packing can be described as layers parallel to the (011) plane, stabilized by intermolecular C—H...O hydrogen bonding, resulting in the formation of an infinite three-dimensional network linking these layers. Strong π–π stacking interactions are observed,viz.benzene–benzene, imidazole–imidazole and benzene–imidazole rings, with centroid–centroid distances of 3.528 (2), 3.457 (2) and 3.544 (2) Å, respectively.
