3,4-Diamino-pyridinium hydrogen succinate.

ABSTRACT: 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.

Bis(2,3-diamino-pyridinium) succinate trihydrate.

Project description:In the title salt, 2C(5)H(8)N(3) (+)·C(4)H(4)O(4) (2-)·3H(2)O, the asymmetric unit contains a protonated 2,3-diamino-pyridinium cation, half of a succinate dianion (disposed about a centre of inversion), and one and a half water mol-ecules. One of the water mol-ecules is disordered over two sites with occupancies of 0.670?(17) and 0.330?(17). The other water mol-ecule has an occupancy of 0.5 (from refinement). The pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The protonated N atom and one of the 2-amino H atoms are hydrogen bonded to the succinate anion through a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the crystal, mol-ecules are consolidated into a three-dimensional network by N-H?O and O-H?O inter-actions.

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.

Bis(2,6-diamino-pyridinium) hydrogen phthalate nitrate monohydrate.

Project description:The title hydrated salt, 2C(5)H(8)N(3) (+)·C(8)H(5)O(4) (-)·NO(3) (-)·H(2)O, was obtained fortuitously from the reaction between 2,6-diamino-pyridine, phthalic acid and Co(NO(3))(2)·6H(2)O at 343?K. The asymmetric unit consists of two crystallographically independent 2,6-diamino-pyridinium cations, a hydrogen phthalate anion, a nitrate ion and a water mol-ecule of crystallization which in the crystal structure are linked by inter-molecular O-H?O and N-H?O hydrogen bonds into a three-dimensional network. In the hydrogen phthalate anion, there is a very strong intra-molecular O-H?O hydrogen bond.

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.
