Abstract: The title compound, C16H18N2O, an N-benzylideneaniline derivative with substituents on both aromatic rings, crystallizes with two independent molecules (A and B) in the asymmetric unit. Both molecules exist in the E configuration. The dihedral angle between the two aromatic rings is 8.20 (5)° for molecule A and 12.52 (6)° for molecule B, and the imino C—N torsion angle (τ) is 7.1 (2)° for molecule A and 14.7 (2)° for molecule B. In the crystal structure, molecules are arranged in stacks which propagate along the a-axis direction. The crystal structure is stabilized by a number of weak C—H...π interactions.

Abstract: In the title compound, [Co(C16H16NO2)3], the CoIII atom is six-coordinated in an irregular octahedral geometry by three N,O-chelating 2-{[2-(4-methoxyphenyl)ethyl]iminomethyl}phenolate groups. One of the three methoxy group is disordered over two sets of sites with an occupancy ratio of 0.768 (5):0.232 (5). The crystal packing can be described by alternating zigzag layers of organic ligands and CoN3O3 octahedra along the c axis. There are no classical hydrogen bonds in the structure, but C—H...π interactions occur.

Abstract: In the title complex, [ZnI2(C13H12N2O)], the ZnII atom has a distorted tetrahedral coordination. The organic ligand is bidentate, coordinating the ZnII atom via the two N atoms. The benzene and pyridine rings are oriented at a dihedral angle of 11.67 (9)°. In the crystal, weak C—H...I and C—H...O hydrogen bonds are observed, in addition to π–π stacking interactions, with a centroid–centroid distance of 3.72 (5) .

Abstract: The title compound, C15H15NO3, adopts the enol–imine tautomeric form. The two rings are twisted with respect to each other, making a dihedral angle of 44.08 (5)°. The 3-methoxy-2-[(E)-(4-methoxyphenyl)-iminomethyl]phenol unit is almost planar, the largest deviation from the mean plane being 0.047 (2) . Such a planar conformation might be related to the occurrence of an intramolecular O—H...N hydrogen bond. In the crystal, intermolecular C—H...O hydrogen bonds link the molecules into sheets parallel to (010). These sheets are interconnected by weak C—H...π interactions.

Abstract: The title Schiff base compound, C14H12N2O4, is in an intermediate state between NH and OH tautomers. Apart from the intramolecular O—H...N hydrogen bond, there are intermolecular C—H...O hydrogen bonds, generating centrosymmetric R22(18) and R22(14) dimers.

Abstract: In the title molecule, C12H17NO2, the amide (N—C=O) plane is oriented at an angle of 33.9 (1)° with respect to the aromatic ring. This is accompanied by an intramolecular C—H...O hydrogen bond. The methoxy group lies almost in the plane of the benzene ring [C–O–C–C torsion angle = 2.7 (2)°]. In the crystal structure, intermolecular N—H...O hydrogen bonds link the molecules into chains along [010].

Abstract: In the title compound, C13H13NO3S, the benzene ring of the benzenesulfonamide moiety is disordered with an occupancy ratio of 0.56 (3):0.44 (3), the disorder components being twisted at and angle of 21 (1)° to each other. The methoxybenzene group is roughly planar (r.m.s. deviation = 0.0144 ) and the amide N atom is displaced from this plane by 0.090 (6) . The dihedral angles between the methoxybenzene group and the major and minor occupancy components of the disordered benzene ring are 54.6 (4) and 62.9 (5)°, respectively. In the crystal, infinite polymeric chains are formed along [100] due to intermolecular N—H...O hydrogen bonding. Weak C—H...π interactions are also present in the crystal.

Abstract: The title compound, C11H14N2O2, was prepared by the reaction of acetohydrazide and 1-(4-methoxyphenyl)ethanone. In the molecule, all bond lengths and angles are within normal ranges. In the crystal structure, adjacent molecules are linked into a centrosymmetric dimer by intermolecular N—H...O hydrogen bonding.

Abstract: The title anilide–imine compound, C24H26N2O, features an intramolecular N—H...N hydrogen bond involving the imine and anilide groups to generate an S(6) ring motif. The molecule displays an E configuration about the imine C=N double bond, with the dihedral angle between the two benzene rings being 86.5°. The packing is stabilized by three different C—H...π interactions.

Abstract: In the title Schiff base, C15H14FN, the N=C bond length of 1.263 (2) is shorter than the N—C bond [1.426 (2) ], indicating a typical imine double bond. Moreover, the C—N—C angle is 118.5 (2)°. The benzene rings form a dihedral angle of 51.22 (5)°.
