2-Amino-3-nitropyridinium hydrogen oxalate
In the non-centrosymetric title compound, C(5)H(6)N(3)O(2) (+)·C(2)HO(4) (-), the hydrogen oxalate anions form corrugated chains parallel to the c axis, linked by O-H⋯O hydrogen bonds. The 2-amino-3-nitro-pyridinium cations are anchored between theses chains by N-H⋯O and C-H⋯O hydrogen bonds and van der Waals and electrostatic inter-actions, creating a three-dimensional network.

In the cation of the title mol-ecular salt, C5H6N3O2 (+)·C2HO4 (-), the dihedral angle between the aromatic ring and the nitro group is 3.5 (3)°; in the anion, the dihedral angle between the CO2 and CO2H planes is 10.5 (2)°. In the crystal, the anions are linked into [100] chains by O-H⋯O hydrogen bonds. The cations cross-link the chains by way of N-H⋯O hydrogen bonds and the structure is conso...
متن کامل3-Cyanoanilinium hydrogen oxalate hemihydrate
In the title hydrated mol-ecular salt, C(7)H(7)N(2) (+)·C(2)HO(4) (-)·0.5H(2)O, contains a 3-cyano-anilinium cation, a hydrogen oxalate anion and half a water mol-ecule in an asymmetric unit. The dihedral angle between the CO(2)(H) and CO(2) planes of the hydrogen oxalate ion is 7.96 (1)°. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming a layer lying paralle...
