Crystal structure of 4-bromo-N-(2-hydroxyphenyl)benzamide
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 2-nitro-N-(2-nitrophenyl)benzamide
In the title compound, C13H9N3O5, the mean plane of the non-H atoms of the central amide fragment C-N-C(=O)-C [r.m.s. deviation = 0.0442 Å] forms dihedral angles of 71.76 (6) and 24.29 (10)° with the C-bonded and N-bonded benzene rings, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds forming C(4) chains along [100]. Weak C-H⋯O contacts link the mol-ecules into (100) ...
متن کاملCrystal structure of 4-methoxy-N-(piperidine-1-carbonothioyl)benzamide
In the title compound, C14H18N2O2S, the piperidine ring has a chair conformation. Its mean plane is twisted with respect to the 4-meth-oxy-benzoyl ring, with a dihedral angle of 63.0 (3)°. The central N-C(=S)-N(H)-C(=O) bridge is twisted with an N-C-N-C torsion angle of 74.8 (6)°. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming chains along the c-axis direction....
متن کاملCrystal structure of N-(propan-2-ylcarbamothioyl)benzamide
In the crystal structure of the title compound, C11H14N2OS, the six atoms of the central C2N2OS residue are coplanar (r.m.s. deviation = 0.002 Å), which facilitates the formation of an intra-molecular N-H⋯O hydrogen bond, which closes an S(6) loop. The terminal phenyl ring is inclined with respect to the central plane [dihedral angle = 42.10 (6)°]. The most prominent feature of the crystal pack...
متن کاملCrystal structure of 2-benzamido-N-(2,2-diethoxyethyl)benzamide
In the title compound, C20H24N2O4, both peptide bonds adopt a trans configuration with respect to the -N-H and -C=O groups. The dihedral angle between the aromatic rings is 53.58 (4)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The crystal packing is characterized by zigzag chains of N-H⋯O hydrogen-bonded mol-ecules running along the b-axis direction.
