(E)-ethyl 4-chloro-3-[2-(2-fluorophenyl)-hydrazono]butanoate
(Int Union Crystallography, 2005)
The title compound, C12H12ClFN2O3, adopts a keto-hydrazo tautomeric form stabilized by an intramolecular N-H (. . .) O hydrogen bond. The whole molecule is roughly planar, the largest deviation from the mean plane being ...
Z)-3-hydroxy-6-[(2-methoxyphenylamino)-methylene]cyclohexa-2,4-dienone
(Int Union Crystallography, 2005)
The title compound, C14H13N1O3, adopts the keto-amine tautomeric form, with an intramolecular N - H (...) O resonance-assisted hydrogen bond. The two benzene rings are nearly coplanar [dihedral angle = 14.3 (2)degrees]. ...
Redetermination of bis(O,O '-dicyclohexyl phosphorodithioato)nickel(II)
(Blackwell Publishing, 2005)
The structure of the title compound, [Ni(C12H22O2PS2)(2)], has been determined previously [Chichang et al. (1987). Chin. J. Struct. Chem. 6, 186], but the current determination provides a significant increase in the precision ...
1-Methoxyethyl-5-nitrobenzimidazole
(Int Union Crystallography, 2005)
The title compound, C10H11N3O3, was synthesized by the reaction of 5-nitrobenzimidazole, 2-chloroethyl methyl ether and KOH in ethanol. The bond lengths and angles are unexceptional.
Ethyl 4-chloro-3-oxo-2-(phenylhydrazono)butyrate
(Int Union Crystallography, 2005)
The title compound, C12H13ClN2O3, adopts a keto-hydrazo tautomeric form stabilized by an intramolecular N-(HO)-O-... hydrogen bond. The configuration around the C = N bond is trans. The dihedral angle between the aromatic ...
1-Benzyl-2-[1-(5-methyl-1H-pyrazol-3-yl)-2-phenylethyl]benzimidazole
(Blackwell Publishing, 2005)
The title compound, C26H24N4, contains one pyrazole ring and two phenyl rings, which are nearly perpendicular to the benzimidazole ring system. In the structure, there is one intramolecular C - H (. . .) N hydrogen-bonding ...
O,O-Bis(2-tert-butyl-4-methoxyphenyl) chlorothiophosphonate
(Int Union Crystallography, 2005)
The title compound, C22H30ClO4PS, displays distorted tetrahedral geometry around the P atom. The dihedral angle between the benzene rings is 41.2 ( 2) degrees. Because of the steric effects of the tert-butyl groups, the ...
Ethyl 3-methyl-1-oxo-4H-1,4-benzothiazine-2-carboxylate
(Blackwell Publishing, 2005)
The crystal structure of the title compound, C12H13NO3S, is stabilized by intermolecular N - H (. . .) O hydrogen bonds, which are formed between the NH groups and the sulfoxide O atoms.
O,O-Bis(2-tert-butyl-4-methylphenyl) chlorothiophosphonate
(Int Union Crystallography, 2005)
The title compound, C22H30ClO2PS, displays distorted tetrahedral geometry around the P atom. The dihedral angle between the benzene rings is 43.7 ( 4) degrees. The aromatic rings have unusual endocyclic angles as a result ...
1,3-Bis(4-methylphenyl)triazene, 1-(4-chlorophenyl)-3-(4-fluorophenyl)triazene and 1-(4-fluorophenyl)3-(4-methylphenyl)triazene
(Int Union Crystallography, 2005)
The title 4,4'-disubstituted diphenyl-1,3-triazines, C14H15N3, (I), C12H9ClFN3, (II), and C13H12FN3, (III), each contain a triazene group (-N=N-NH-) having an extended conformation. The dihedral angles between the two ...
