Abstract

The title compound, C16H14Cl2N2O2, is a Schiff base compound, derived from the condensation of 5-chlorosalicylaldehyde and ethane-1,2-diamine in MeOH. The molecule lies about an inversion centre at the mid-point of the C—C bond of the ethylenediamine unit. Intramolecular O—H…N hydrogen bonds contribute to the planarity of the aromatic imide units of the molecule. [ABSTRACT FROM AUTHOR]

Abstract

In the title compound, C24H18F3N3O, the molecule exists in the enamine–keto tautomeric form. The pyrazolone ring makes dihedral angles of 31.8 (2), 45.4 (2) and 71.2 (2)° with the 1-phenyl, aniline and methylene-bound phenyl rings, respectively. An intramolecular N—H...O hydrogen bond helps to stabilize the molecular conformation. [ABSTRACT FROM AUTHOR]
