Crystal structure of 4-bromo-N-(2-bromo-3-nitrobenzyl)-2-nitronaphthalen-1-amine
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, C13H10BrNO2, the mean plane of the non-H atoms of the central amide C-N-C(=O)-C fragment (r.m.s. deviation = 0.004 Å) forms a dihedral angle of 73.97 (12)° with the hy-droxy-substituted benzene ring and 25.42 (19)° with the bromo-substituted benzene ring. The two aromatic rings are inclined to one another by 80.7 (2)°. In the crystal, mol-ecules are linked by O-H⋯O and N-...
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...

The title compound, C(18)H(18)Br(2)N(2), is centrosymmetric with the mid-point of the central C-C bond of the butyl group located on an inversion center. The terminal benzene ring is approximately perpendicular to the central butyl plane [dihedral angle = 71.9 (8)°]. No hydrogen bonding or aromatic stacking is observed in the crystal.
متن کاملCrystal structure of 2-bromo-3-dimethylamino-N,N,N′,N′,4-pentamethyl-4-(trimethylsilyloxy)pent-2-eneamidinium bromide
The reaction of the ortho-amide 1,1,1-tris-(di-methyl-amino)-4-methyl-4-(tri-methyl-sil-yloxy)pent-2-yne with bromine in benzene, yields the title salt, C15H33BrN3OSi(+)·Br(-). The C-N bond lengths in the amidinium unit are 1.319 (6) and 1.333 (6) Å, indicating double-bond character, pointing towards charge delocalization within the NCN plane. The C-Br bond length of 1.926 (5) Å is characterist...
