7,7a-Dihydroisoindolo[2,1-a]pyrimidin-12-one
(Int Union Crystallography, 2006)
The crystal structure of the title compound, C18H12N2O, is stabilized by intermolecular N-H (...) O hydrogen bonds and C-H (...) pi interactions. N-H (...) O hydrogen bonds generate a C( 6) chain. The dihedral angle between ...
3-Anilinoisobenzofuran-1(3H)-one
(Int Union Crystallography, 2006)
Crystals of the title compound, C14H11NO2, are stabilized by an intermolecular N-H (...) O hydrogen bond and a weak pi-pi interaction. N-H (...) O hydrogen-bond interactions generate C(6) chains. The phthalide section of ...
(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 ...
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 ...
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 ...
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 ...
(2-Hydroxyethy1)hydraziniurn(2+) dichloride
(Blackwell Munksgaard, 2005)
The crystal structure of the title compound, C2H10N2O2+• 2Cl(-), is built up from one 2-hydroxyethylhydrazinium(2+) cation and two Cl- anions. The molecular structure is stabilized by O-H••• Cl and ...
