4-Bromo-2-[(E)-(2-{2-[(2-{[(E)-5-bromo-2-hydroxybenzylidene]amino}phenyl)sulfanyl]ethylsulfanyl}phenyl)iminomethyl]phenol
The asymmetric unit of the title compound, C(28)H(22)Br(2)N(2)O(2)S(2), comprises half of a Schiff base ligand, the whole mol-ecule being generated by a crystallographic inversion center located at the mid-point of the C-C bond of the central methyl-ene segment. Intra-molecular O-H⋯N and O-H⋯S hydrogen bonds make S(6) and S(5) ring motifs, respectively. In the crystal, there are no significant ...

The title compound, C(20)H(23)BrN(2)O(2), containing an ibuprofen core, crystallizes with three independent mol-ecules of similar conformation in the asymmetric unit. In these three mol-ecules, the two benzene rings make dihedral angles of 82.7 (2), 71.2 (2) and 78.0 (3)° with respect to each other. The atoms of the isobutyl groups in two of the mol-ecules are disordered over two positions, wit...
متن کامل4-Bromo-2-[(E)-(2-fluoro-5-nitrophenyl)iminomethyl]phenol
The mol-ecular conformation of the title compound, C13H8BrFN2O3, is essentially planar, with maximum deviations of 0.076 (1) and -0.080 (2) Å for the O atoms of the NO2 group. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, forming an S(6) ring motif. In the crystal, pairs of mol-ecules are linked via two pairs of C-H⋯O hydrogen bonds, forming inversion dime...
