5-Amino-4-bromo-2,3-dihydro-1H-inden-1-one
In the title compound, C(9)H(8)BrNO, the non-H-atom framework is essentially planar, with a maximum deviation of 0.087 (3) Å. In the crystal, mol-ecules are inter-connected into a three-dimensional network by C-H⋯O and N-H⋯O hydrogen bonds. In addition, C-H⋯π inter-actions and a π-π stacking inter-action, with a centroid-centroid distance of 3.5535 (19) Å, are also observed.

In the mol-ecule of the title compound, C(10)H(9)N(3)O(2), the pyrazole ring is approximately coplanar with the amino and carboxyl groups. The phenyl group is twisted by 48.13 (3)° relative to this plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation of the mol-ecule. The mol-ecules are linked into two-dimensional sheets by two strong inter-molecular N-H⋯N and O-H⋯O ...

The title compound, C(17)H(17)N(5)O, exists in the zwitterionic form with the amide group deprotonated. The mean planes of the 1,2,4-triazole and N-phenyl rings form a dihedral angle of 39.14 (8)°. The N atom of the amino group adopts a trigonal configuration. Inter-moleculat C-H⋯O and C-H⋯N hydrogen bonds occur. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (...

The structure of the title compound, C(8)H(9)N(3), a potential anti-tumour drug, was determined in order to give more insight into its structure-function relationships. The benzimidazole core of the mol-ecule was found to be exactly planar, while the substituents are displaced slightly from the mol-ecular plane [C-C-N-C and C-C-C-N torsion angles of 0.8 (3) and 179.0 (1)° for the methyl and ami...
متن کامل2-Amino-5-bromopyridine–4-hydroxybenzoic acid (1/1)
The title 1:1 adduct, C(5)H(5)BrN(2)·C(7)H(6)O(3), contains two mol-ecules of each species in the asymmetric unit, with similar geometries. In the crystal, mol-ecules are linked to form extended chains along [100] by N-H⋯O, O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds. Adjacent chains are crosslinked via further N-H⋯O inter-actions into sheets lying parallel to (001). The crystal studied was an invers...
