Methyl 2-amino-5-bromobenzoate
In the title compound, C(8)H(8)BrNO(2), the dihedral angle between the aromatic ring and the methyl acetate side chain is 5.73 (12)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring. In the crystal, mol-ecules are connected by N-H⋯O inter-actions, generating zigzag chains running along the b-axis direction.
متن کاملMethyl 2-amino-5-chlorobenzoate
The title compound, C(8)H(8)ClNO(2), is almost planar, with an r.m.s. deviation of 0.0410 Å from the plane through the non-hydrogen atoms. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the b axis. An intra-molecular N-H⋯O hydrogen bond results in the formation of a six-membered ring.
متن کاملCrystal structure of bis(2-amino-5-chloropyridinium) tetrachloridocobaltate(II)
The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)(+) cations [maximum deviations = 0.010 (3) and 0.014 (3) Å] that are nearly perpendicular to each other [dihedral angle = 84.12 (7)°]. They are bonded through N-H⋯Cl hydrogen bonds to distorted [CoCl4](2-) tetra-hed...
متن کاملCrystal structure of 2-amino-5-nitropyridinium sulfamate
The title mol-ecular salt, C5H6N3O2 (+) ·H2NO3S(-), was obtained from the reaction of sulfamic acid with 2-amino-5-nitro-pyridine. A proton transfer from sulfamic acid to the pyridine N atom occurred, resulting in the formation of a salt. As expected, this protonation leads to the widening of the C-N-C angle of the pyridine ring, to 122.9 (3)°, with the pyridinium ring being essentially planar ...
متن کاملCrystal structure of 5-(5-chloro-2-hydroxybenzoyl)-2-(2-methyl-1H-indol-3-yl)nicotinonitrile
In the title compound, C22H14ClN3O2, the indole unit is essentially coplanar, with a maximum deviation of 0.035 Å for the C atom bearing the methyl group. The central pyridine ring is inclined to the indole ring system by 43.7 (1)°. The dihedral angle between the phenyl ring and the indole ring system is 15.7 (2)°, while that between the phenyl ring and the central pyridine ring is 46.3 (1)°. T...
