چکیده
Except two F atoms of the -CF(3) group, the title compound, C(14)H(8)BrF(3)N(2)O(3), has an almost planar conformation, the dihedral angle between the aromatic rings being 3.60 (16)°. The mol-ecule adopts the enol-imine tautomeric form, with an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring motif. In the crystal, face-to-face π-π stacking [centroid-centroid distances = 3.669 (2) and 3.732 (2) Å] between the aromatic rings of the mol-ecules, which lie in sheets parallel to (202), help to establish the packing.

Mol-ecules of the title compound, C(34)H(38)N(4)O(2), lie across crystallographic inversion centres. The crystal packing can be described by alternating zigzag chains along the c axis in which the molecules are linked by van der Waals interactions. There is an intra-molecular O-H⋯N hydrogen bond and the two benzene rings in the asymmetric unit make a dihedral angle of 79.81 (6)°.

In the title compound, C(17)H(20)N(2)O(3), the amino N atom is in a planar environment (sum of angles = 360.0°). All hy-droxy H atoms are involved in hydrogen bonding. In the crystal structure, two O-H⋯O and an O-H⋯N(imino) hydrogen bond result in the formation of a three-dimensional network. The latter hydrogen bonding causes distortion of the planarity of the 4-HO-C(6)H(4)-CH=N-C(6)H(4)- frag...

The title mol-ecule, C(32)H(24)N(2)O(2), has a crystallographically imposed inversion centre and exists in the crystal as an enol-imine tautomer. The mol-ecular structure is stabilized by two strong intra-molecular O-H⋯N hydrogen bonds. The dihedral angles between the central benzene ring and the mean planes of the phenyl substituents are 59.99 (1) and 62.79 (2)°. In the crystal, the mol-ecules...

In the title compound, C(14)H(11)BrN(2)O(2), the mean planes of the two benzene rings are almost parallel to each other, making a dihedral angle of 4.09 (1)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, inter-molecular O-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a chain-like supra-molecular structure.
