All the residues of the title compound, (C(5)H(6)N(3)O(2))[ReO(4)]·H(2)O, are located on general crystallographic positions. The 2-amino-5-nitro-pyridinium cation has a typical planar conformation with one of the nitro O atoms -0.058 (5) Å out of plane; the amine H atoms are also a little out of the main ring plane towards the opposite side of the aforementioned O atom [by 0.02 (4) and 0.04 (4)...

The title compound, C(12)H(10)N(2)O(2)·H(2)O, crystallizes as a zwitterion in which the pyridine N atom is protonated and the carb-oxy -OH group is deprotonated. The benzene and pyridinium rings are inclined with a dihedral angle of 6.63 (5)° between them. In the crystal, inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions link adjacent mol-ecules into a two-dimensional double layere...

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...
متن کامل4-[(2-Carboxyethyl)amino]benzoic acid monohydrate
In the title compound, C(10)H(11)NO(4)·H(2)O, the carboxyl group is twisted at a dihedral angle of 6.1 (3)° with respect to the benzene ring. In the crystal, the organic mol-ecules are linked by pairs of O-H⋯O hydrogen bonds involving both carboxyl groups, forming zigzag chains propagating along the b-axis direction. The water mol-ecules form [100] chains linked by O-H⋯O hydrogen bonds. The org...
