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

ABSTRACT: 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.

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.

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.

2-Amino-5-chloro-pyridinium salicylate.

Project description:In the crystal structure of the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(3) (-), the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming R(2) (2)(8) ring motifs. These motifs are centrosymmetrically paired via N-H⋯O hydrogen bonds, forming a complementary donor-donor-acceptor-acceptor (DDAA) array. A typical intra-molecular O-H⋯O hydrogen bond is also observed in the salicylate anion. The crystal structure is further stabilized by weak C-H⋯π inter-actions.

2-Amino-5-chloro-pyridinium trifluoro-acetate.

Project description:The asymmetric unit of the title salt, C(5)H(6)ClN(2) (+)·C(2)F(3)O(2) (-), contains two independent 2-amino-5-chloro-pyridinium cations and two independent trifluoro-acetate anions.

In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001).

2-Acetyl-pyridinium 3-amino-2-chloro-pyridinium tetra-chloridocobaltate(II).

Project description:In the title complex, (C(5)H(6)ClN(2))(C(7)H(8)NO)[CoCl(4)], the Co(II) ions are tetra-hedrally coordinated. The crystal structure is built from hydrogen-bonded centrosymmetric tetra-mers of tetra-chloridocobaltate(II) dianions and 3-amino-2-chloro-pyridinium cations, additionally strengthened by significant π-π stacking of pyridinium rings [interplanar distance 3.389 (3) Å]. The tetra-mers are linked by N-H⋯Cl hydrogen bonds into chains; the second kind of cations, viz. 2-acetyl-pyridinium, are connected by N-H⋯Cl hydrogen bonds to both sides of the chain. The Co-Cl bond lengths in the dianion correlate with the number of hydrogen bonds accepted by the Cl atom. An intramolecular C-H⋯Cl interaction is also present.
