3,4-Di-amino-pyridinium hydrogen malonate.

ABSTRACT: In the title salt, C5H8N3 (+)·C3H3O4 (-), the 3,4-di-amino-pyridinium cation is almost planar, with an r.m.s. deviation of 0.02?Å. The conformation of the hydrogen malonate anion is stabilized by an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring. In the crystal, N-H?O hydrogen bonds link cations and anions into layers parallel to the ab plane.

2,3-Diamino-pyridinium hydrogen malonate.

Project description:In the title mol-ecular salt, C5H8N3(+)·C3H3O4(-), the cation is essentially planar, with a maximum deviation of 0.005?(1)?Å for all non-H atoms. In the anion, an intra-molecular O-H?O hydrogen bond generates an S(6) ring. In the crystal, the cations and anions are connected via N-H?O hydrogen bonds and a weak C-H?O inter-action, forming layers parallel to the ab plane.

3,4-Diamino-pyridinium hydrogen succinate.

Project description:In the title compound, C(5)H(8)N(3) (+)·C(4)H(5)O(4) (-), the pyridine N atom of the 3,4-diamino-pyridine mol-ecule is protonated. The protonated N atom participates in an N-H?O hydrogen bond to a succinate O atom of the singly deprotonated succinate anion. Each of the two amino groups are hydrogen-bonded to the O atoms of two different sets of succinate groups.. The crystal structure is further stabilized by O-H?O and C-H?O hydrogen bonds.

Tetra-kis(2-amino-5-chloro-pyridinium) di-hydrogen cyclo-hexa-phosphate.

Project description:In the crystal structure of the title compound, 4C5H6ClN2 (+)·H2P6O18 (4-), the [H2P6O18](4-) anions are interconnected by O-H?O hydrogen bonds, leading to the formation of infinite ribbons extending along the a-axis direction. These ribbons are linked to the organic cations, via N-H?O and C-H?O hydrogen bonds, into a three-dimensional network. The six P atoms of the [H2P6O18](4-) anion form a chair conformation. The complete cyclohexaphosphate anion is generated by inversion symmetry.

Tetrakis(2,6-di-methyl-pyridinium) di-hydrogen deca-vanadate dihydrate.

Project description:The structure of the title compound, (C7H10N)4[H2V10O28]·2H2O, was solved from a non-merohedrally twinned crystal (ratio of twin components ?0.6:0.4). The asymmetric unit consists of one-half deca-vanadate anion (the other half completed by inversion symmetry), two 2,6-di-methyl-pyridinium cations and one water mol-ecule of crystallization. In the crystal, the components are connected by strong N-H?O and O-H?O hydrogen bonds, forming a supra-molecular chain along the b-axis direction. There are weak C-H?O inter-actions between the chains.

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 oxalate.

Project description: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-5-bromo-pyridinium hydrogen succinate.

Project description:In the title compound, C(5)H(6)BrN(2) (+)·C(4)H(5)O(4) (-), the pyridine N atom of the 2-amino-5-bromo-pyridine mol-ecule is protonated. The protonated N atom and the amino group are linked via N-H?O hydrogen bonds to the carboxyl-ate O atoms of the singly deprotonated succinate anion. The hydrogen succinate anions are linked via O-H?O hydrogen bonds. A weak inter-molecular C-H?O hydrogen bond is also observed.

2-Amino-5-chloro-pyridinium hydrogen succinate.

Project description:In the title salt, C(5)H(6)ClN(2) (+)·C(4)H(5)O(4) (-), the pyridine N atom is protonated. The pyridinium and amino groups associate via a pair of N-H⋯O hydrogen bonds to the carboxyl-ate O atoms of the singly deprotonated succinate anion. The hydrogen succinate anions self-assemble via O-H⋯O hydrogen bonds into chains along the b axis. The crystal structure is further stabilized by additional N-H⋯O hydrogen bonds involving the second amino H atoms, as well as C-H⋯O contacts, forming a three-dimensional network.

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.

Project description:In the title salt, C(5)H(7)N(2) (+)·C(4)H(5)O(4) (-), the asymmetric unit comprises an amino-pyridinium cation and a hydrogen succinate anion as protonation of the aromatic N atom of the 4-amino-pyridine mol-ecule has occurred. The crystal packing is stabilized by inter-molecular O-H?O and N-H?O hydrogen bonds that lead to a two-dimensional array. Short C-H?O contacts are also present.
