(E)-N'-(5-Bromo-2-hy-droxy-benzyl-idene)-2-(4-isobutyl-phen-yl)propano-hydrazide.

ABSTRACT: 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, with site-occupancy ratios of 0.516?(8):0.484?(8) and 0.580?(8):0.420?(8). In the crystal, mol-ecules are linked by N-H?O, C-H?O and O-H?N hydrogen bonds. Furthermore, C-H?? inter-actions are also observed.

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, with site-occupancy ratios of 0.516 (8):0.484 (8) and 0.580 (8):0.420 (8).

Project description:The mol-ecule of the title compound, C(10)H(11)N(3)O(3), adopts an all-trans conformation and is approxomately planar, the largest deviation from the least-squares plane through all non-H atoms being 0.261 (1) Å. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the mol-ecules are packed into layers lying parallel to the ab plane by π-stacking inter-actions between the benzene ring of one molecule and the C-N bond of the oxime group of another molecule; the shortest inter-molecular C⋯C separation within the layer is 3.412 (1) Å. The layers are connected by O-H⋯O and N-H⋯O hydrogen bonds.

2-(4-Isobutyl-phen-yl)-N'-[(3Z)-2-oxoindolin-3-yl-idene]propano-hydrazide.

Project description:In the title compound, C(21)H(23)N(3)O(2), the indolin-2-one group is essentially planar, with a maximum deviation of 0.016?(2)?Å for the N atom, and makes a dihedral angle of 84.38?(14)° with the benzene ring. The =N-N(H)-C(=O)-C- torsion angle is 0.9?(3)°. In the crystal, mol-ecules are linked into a three-dimensional network via N-H?O and C-H?O hydrogen bonds. In addition, a C-H?? inter-action was observed.

N'-[(E)-4-Bromo-benzyl-idene]-2-(4-isobutyl-phen-yl)propanohydrazide.

Project description:The asymmetric unit of the title compound, C(20)H(23)BrN(2)O, contains two independent mol-ecules (A and B), in which the orientations of the 4-isobutyl-phenyl units are different. The dihedral angle between the two benzene rings is 88.45?(8)° in mol-ecule A and 89.87?(8)° in mol-ecule B. Mol-ecules A and B are linked by a C-H?N hydrogen bond. In the crystal, mol-ecules are linked into chains running along the a axis by inter-molcular N-H?O and C-H?O hydrogen bonds. The crystal structure is further stabilized by C-H?? inter-actions. The presence of pseudosymmetry in the structure suggests the higher symmetry space group Pbca. However, attempts to refine the structure in this space group resulted in a disorder model with high R (0.097) and wR (0.257) values. The crystal studied was an inversion twin with a 0.595?(4):0.405?(4) domain ratio.

(S)-Benzyl 3-(4-hy-droxy-phen-yl)-2-(trityl-amino)-propano-ate.

Project description:The title compound, C(35)H(31)NO(3), was obtained by the reaction of (S)-benzyl 2-amino-3-(4-hy-droxy-phen-yl)propano-ate and (chloro-methane-tri-yl)tribenzene. The enanti-omer has been assigned by reference to an unchanging chiral centre in the synthetic procedure. In the crystal, mol-ecules are linked into chains running along the a axis by inter-molecular O-H?O hydrogen bonds.

{5-Chloro-2-[(2-hy-droxy-benzyl-idene)amino]-phen-yl}(phen-yl)methanone.

Project description:The title Schiff base compound, C(20)H(14)ClNO(2), adopts an E configuration about the azomethine bond. The phenol and chloro-benzene rings form dihedral angles of 84.71?(9) and 80.70?(8)°, respectively, with the phenyl ring and are twisted by 15.32?(8)° with respect to one another. The mol-ecular conformation is stabilized by an intra-molecular O-H?N hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds, forming columns parallel to the a axis.

Project description:The asymmetric unit of the title hydrazone compound, C(15)H(10)BrClN(2)O(4), contains two independent mol-ecules. The dihedral angles between the benzene rings are 38.7 (3)° in one mol-ecule and 24.3 (3)° in the other. Both mol-ecules exist in trans conformations with respect to the C=N double bonds of the central methyl-idene units. Intra-molecular O-H⋯N contacts are observed in both mol-ecules, forming S(6) rings. In the crystal, mol-ecules are linked through N-H⋯O hydrogen bonds into chains along the a axis.

N'-[(1E)-3-Bromo-5-chloro-2-hy-droxy-benzyl-idene]-4-tert-butyl-benzo-hydrazide ethanol monosolvate.

Project description:In the title compound, C(18)H(18)BrClN(2)O(2)·C(2)H(6)O, the hy-droxy group forms an intra-molecular O-H⋯N hydrogen bond, which influences the conformation of the Shiff base mol-ecule, where the two aromatic rings form a dihedral angle of 21.67 (8)°. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link two Shiff base mol-ecules and two solvent mol-ecules into a centrosymmetric heterotetra-mer. Weak inter-molecular C-H⋯O inter-actions link further tetra-mers related by translation along the a axis into chains.

Benzyl N-(2-hy-droxy-1-{N'-[(1E)-2-hy-droxy-benzyl-idene]hydrazinecarbon-yl}eth-yl)carbamate.

Project description:The mol-ecule of the title compound, C(18)H(19)N(3)O(5), adopts a curved arrangement with the terminal benzene rings lying to the same side. The hydroxyl-benzene ring is close to coplanar with the adjacent hydrazine residue [dihedral angle = 11.14?(12)°], an observation which correlates with the presence of an intra-molecular O-H?N hydrogen bond. The benzyl ring forms a dihedral angle of 50.84?(13)° with the adjacent carbamate group. A twist in the mol-ecule, at the chiral C atom, is reflected in the dihedral angle of 80.21?(12)° formed between the amide residues. In the crystal, two-dimensional arrays in the ac plane are mediated by O-H?O and N-H?O hydrogen bonds.
