2-Amino-5-nitropyridinium trifluoroacetate

Studies on the Synthesis, Growth, Characterization of 2-amino- 5-nitropyridinium-toluenesulfonate Single Crystals

5-Amino-2-methyl­benzene­sulfonamide

In the crystal structure of the title compound, C(7)H(10)N(2)O(2)S, a benzoic acid derivative, inter-molecular N-H⋯O inter-actions link the mol-ecules into a three-dimensional network.

2-Amino-3-methyl­pyridinium 2-amino-5-methyl­pyridinium sulfate monohydrate

The asymmetric unit of the title compound, 2C(6)H(9)N(2) (+)·SO(4) (2-)·H(2)O, contains two isomeric protonated amino-methyl-pyridine cations, a sulfate anion and a solvent water mol-ecule. The cations are in the iminium tautomeric form. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the components into a three-dimensional network. Additional stabiliza...

2-Amino-5-chloro­pyridinium trifluoro­acetate

The asymmetric unit of the title salt, C(5)H(6)ClN(2) (+)·C(2)F(3)O(2) (-), contains two independent 2-amino-5-chloro-pyridinium cations and two independent trifluoro-acetate anions. The F atoms of both anions are disordered over two sets of positions, with occupancy ratios of 0.672 (12):0.328 (12) and 0.587 (15):0.413 (15). In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O ...

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.
