Papers
1-((2-Hydroxy-5-methylphenylamino)methylene)naphthalen-2(1H)-one
TL;DR: The C18H15NO2 molecule as mentioned in this paper adopts a keto-amine tautomeric form with an intramolecular N−H⋯O and an intermolecular O−H−O hydrogen bond.

A redetermination of 1- 4-((2-hydroxybenzylidene)amino)phenyl ethanone
TL;DR: The crystal structure of the title compound, C15H13NO2, has been determined with better precision and with the location and free refinement of all H atoms as mentioned in this paper, which is the first step towards the full crystal structure determination.

(E)-4-Meth-oxy-2-(p-tolyl-imino-meth-yl)phenol
TL;DR: The C15H15NO2 compound has a strong intra-molecular O-H⋯N hydrogen bond as a result as discussed by the authors and is almost planar, with a maximum deviation of 0.1038

(Z)-4-(2,6-Dichlorophenyldiazenyl)-6-{[1,3-dihydroxy-2-(hydroxymethyl)propan-2-ylamino]methylene}-2-methoxycyclohexa-2,4-dienone and the 3-methoxyphenyldiazenyl and 4-methoxyphenyldiazenyl analogues.
TL;DR: Three keto–amine tautomeric compounds with strong intramolecular N—H⋯O hydrogen bonds arise as a result of the shifts achieved by the hydroxy H atoms of the Schiff bases to the N atoms.

Crystallographic and Conformational Analysis of [( E )-2-[(3-Chlorophenylimino)methy])-4-methoxyphenol]
TL;DR: In this article, the crystal structure of C14H12ClNO2 was determined by X-ray analysis, and conformational analysis of the title molecule with respect to the selected torsion angle has been achieved by AM1 semi-empirical calculations.
