1-[(2-hydroxy-5-methylphenylamino)-methylene]naphthalen-2(1H)-one
(Int Union Crystallography, 2004)
The molecule of the title compound, C18H15NO2, is not completely planar. It adopts a keto-amine tautomeric form with an intramolecular N-H...O and an intermolecular O-H...O hydrogen bond. The molecules are linked by O-H...O ...
Preparation and characterization of chromophore group containing cyclotriphosphazenes: IV spectroscopic and thermal investigation of some hexakis(p-phenylazo-o-allylphenoxy)cyclotriphosphazenes
(Elsevier Science Bv, 2004)
Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlorocyclotriphosphazene and 3-allyl-4-hydroxyazo compounds such as 3-allyl-4-hydroxyazobenzene,4'-chloro-3-allyl-4-hydroxyazobenzene, ...

A redetermination of 1-{4-[(2-hydroxybenzylidene)amino]phenyl}ethanone
(Blackwell Munksgaard, 2004)
The crystal structure of the title compound, C15H13NO2, has been redetermined with better precision and with the location and free refinement of all H atoms [previous report; Rekhlova, Furmanova, Chanturiya & Chikhladze ...
3-(4-Acetylphenyliminomethyl)-1,2-dihydroxy-benzene
(Int Union Crystallography, 2004)
The molecule of the title compound, C15H13NO3, is not planar and the dihedral angle between the planes of the two aromatic rings is 53.93 (7)degrees. The molecule exists in the crystal structure in the phenol-imine tautomeric ...

(Blackwell Munksgaard, 2004)
…
2-aminopyridinium-fumarate-fumaric acid (2/1/1)
(Int Union Crystallography, 2004)
The title complex, 2C(5)H(7)N(2)(+).C4H2O42-.C4H4O4, contains cyclic eight-membered hydrogen-bonded rings involving 2-aminopyridinium and fumarate ions. The fumaric acid molecules and fumarate ions lie on inversion centers ...
3-hydroxy-6-[(4-hydroxyphenylamino)methylene]cyclohexa-2,4-dienone and 2-hydroxy-6-[(4-hydroxyphenylamino)-methylene]cyclohexa-2,4-dienone
(Int Union Crystallography, 2004)
The title compounds, both C13H11NO3, exist as the keto-amine tautomers, and the formal hydroxyl H atoms, which display strong intramolecular hydrogen bonds, are located on the N atoms. This is a verification of the preference ...
3-methoxy-5-(4-methylphenyldiazenyl)salicylaidehyde and 3-methoxy-5-(2-methylphenyldiazenyl)salicylaldehyde
(Int Union Crystallography, 2004)
The two title molecules, both C15H14N2O3, are roughly planar and display a trans conformation with respect to the -N=N- double bond, as found for other diazene derivatives. In both compounds, there are intramolecular O-H...O ...
2-[2-(hydroxymethyl)phenyliminomethyl]-phenol
(Int Union Crystallography, 2004)
Molecules of the title compound, C14H13NO2, are nearly planar. The molecular structure is stabilized by a strong intramolecular O-H...N hydrogen bond between the imine and hydroxyl groups [O...N = 2.614 (2) Angstrom]. In ...
