2-Amino-5-chloro-pyridinium salicylate.

ABSTRACT: 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?? inter-actions.

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.

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 ?-? 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.
