The mol-ecule of the title compound, [Ni(C(24)H(19)FN(3)O)(2)], has twofold rotation symmetry. The Ni(II) ion is in a square-planar coordination geometry which is distorted towards tetra-hedral and is coordinated by two N atoms of imine and two O atoms of pyrazolone from two Schiff base 4-[(Z)-(4-fluoro-benzyl-amino)phenyl-methyl-ene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-onate ligands.

The title compound, C(23)H(18)ClN(3)O, was synthesized by the reaction of 4-chloro-aniline and 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one. The terminal benzene rings are twisted at dihedral angles of 48.3 (2), 71.4 (2) and 36.1 (2)° with respect to the central eight-atom methyl-pyrazolone/amino-methyl-ene unit. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation [mea...

The title compound, C(20)H(19)N(3)O, exists in a keto-enamine tautomeric form. The pyrazolone ring makes dihedral angles of 20.52 (10) and 77.73 (5)° with the two phenyl rings and an intra-molecular N-H⋯O hydrogen bond occurs. A weak inter-molecular C-H⋯O hydrogen bond is observed in the crystal structure. The allyl group is disordered over two positions, with site-occupancy factors of 0.533 (5...

In the title compound, C(21)H(23)N(3)O, the dihedral angles formed by the pyrazolone ring with two phenyl rings are 10.38 (8) and 76.94 (6)°. The sec-butyl-amino group is disordered over two positions, with refined site-occupancy factors of 0.730 (4) and 0.270 (4). The compound could potentially be ligand stabilized in the solid state in a keto-enamine tautomeric form. The amine functionality i...
