6-Bromo-2-naphthol–piperazine (2/1)
In the title compound, 2C(10)H(7)BrO·C(4)H(10)N(2), the piperazine (pip) mol-ecule displays a chair conformation and is linked to two mol-ecules of 6-bromo-2-naphthol (bno) via O-H⋯N hydrogen bonds. Weak N-H⋯O hydrogen bonds from pip to bno mol-ecules result in chains propagating in [100]. The chains inter-act via C-H⋯π inter-actions.

In the title compound, C17H11Br2N3O4, the dihedral angle between the planes of the naphthalene system and the benzene ring is 52.86 (8)°. The nitro substituent and the attached naphthalene system are almost coplanar [dihedral angle = 5.6 (4)°], probably as a consequence of an intra-molecular N-H⋯O hydrogen bond with the amine group. The nitro substituent attached to the benzene ring is disorder...

In the title compound, C12H9BrSe, the Se atom exhibits a bent geometry, with a C-Se-C bond angle of 99.19 (6)°. The ortho Se and Br atoms are slightly displaced from opposite faces of the mean plane of the benzene ring [by 0.129 (2) and 0.052 (2) Å, respectively]. The planes of the benzene and phenyl rings form a dihedral angle of 72.69 (5)°. In the crystal, π-stacking inter-actions between inv...

In the title compound, C6H4BrN3O4, the dihedral angles between the nitro groups and the aniline ring are 2.04 (3) and 1.18 (4)°, respectively. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds and weak side-on C-Br⋯π inter-actions [3.5024 (12) Å] link adjacent mol-ecules, forming a three-dimensional network. A close O⋯Br contact [3.259 (2) Å] may also add additional stability.
متن کاملCrystal structure of 3-bromo-2-hydroxybenzonitrile
The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial mol-ecular packing disorder such that a 180° rotation of the mol-ecule about the phenol C-O bond results in disorder of the bromine and nitrile groups. The disorder has been parameterized as a disorder of only the bromine and nitrile substituents on a unique phenol ring. An intra-molecular O-H⋯Br con...
