The Crystallographic, Spectroscopic and Theoretical Studies on (E)-2-[((4-fluorophenyl)imino)methyl]-4-nitrophenol and (E)-2-[((3-fluorophenyl)imino)methyl]-4-nitrophenol Compounds

In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...

6-Chloro-2-(4-meth­oxy­phen­yl)-4-phenyl­quinoline

In the title compound, C22H16ClNO, the quinoline ring system makes dihedral angles of 56.30 (6) and 7.93 (6)°, respectively, with the adjacent phenyl and benzene rings. The dihedral angle between these phenyl and benzene rings is 56.97 (8)°. In the crystal, weak C-H⋯π and π-π [centroid-centroid distances of 3.7699 (9) and 3.8390 (9) Å] inter-actions link the mol-ecules into a layer parallel to ...

2-(4-Chloro­phen­yl)-6-meth­oxy­chroman-4-one

In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.

6-(4-Amino­phen­yl)-2-meth­oxy-4-phenyl­nicotino­nitrile

In the structure of the title nicotino-nitrile derivative, C19H15N3O, the pyridine ring makes dihedral angles of 11.50 (7) and 43.36 (8)° with the 4-amino-phenyl and phenyl rings, respectively, and the dihedral angle between the phenyl rings is 36.28°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into wave-like sheets parallel to (10-2). These sheets are stacked by π-π inter-ac...
