2-Amino-5-nitro-pyridinium hydrogen oxalate.

ABSTRACT: 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 consolidated by C-H?O inter-actions.

2-Amino-3-nitro-pyridinium hydrogen oxalate.

Project description: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.

2-Amino-3-nitro-pyridinium hydrogen selenate.

Project description:The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·HSeO(4) (-), contains two monoprotonated 2-amino-3-nitro-pyridinium cations and two hydrogen selenate anions which are connected through N-H?O and O-H?O hydrogen bonds, building chains parallel to the a direction. These chains are further connected to each other by weaker C-H?O hydrogen-bonding inter-actions, leading to the formation of a three-dimensional network.

2-Amino-5-nitro-pyridinium hydrogen selenate.

Project description:There are two cations and two anions in the asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·HSeO(4) (-). In the crystal, there are two independent chains of HSeO(4) (-) anions running along the a axis, linked by O-H?O hydrogen bonds. Ribbons of cations linked by N-H?O hydrogen bonds run along the b-axis direction, and are further hydrogen bonded to the anions by N-H?O and C-H?O links, generating a three-dimensional network.

Bis(2,6-diamino-pyridinium) bis-(hydrogen oxalate) monohydrate.

Project description:The asymmetric unit of the title compound, 2C(5)H(8)N(3) (+)·2C(2)HO(4) (-)·H(2)O, contains two crystallographically independent 2,6-diamino-pyridinium cations, a pair of hydrogen oxalate anions and a water mol-ecule. Both 2,6-diamino-pyridinium cations are planar, with maximum deviations of 0.011?(2) and 0.015?(1)?Å, and are protonated at the pyridine N atoms. The hydrogen oxalate anions adopt twisted conformations and the dihedral angles between the planes of their carboxyl groups are 31.01?(11) and 63.48?(11)°. In the crystal, the cations, anions and water mol-ecules are linked via O-H?O and N-H?O hydrogen bonds, forming a three-dimensional network.

2-Amino-3-nitro-pyridinium perrhenate.

Project description:In the title mol-ecular salt, (C(5)H(6)N(3)O(2))[ReO(4)], the cations and tetrahedral anions are linked by trifurcated N-H?(O,O,O) and bifurcated N-H?(O,O) hydrogen bonds, as well as weak C-H?O inter-actions. This results in alternating corrugated inorganic and organic layers in the crystal.
