2-Acetyl-pyridinium bromanilate.

Project description:In the crystal of the title mol-ecular salt (systematic name: 2-acetyl-pyridinium 2,5-dibromo-4-hydr-oxy-3,6-dioxocyclo-hexa-1,4-dienolate), C(7)H(8)NO(+)·C(6)HBr(2)O(4) (-), centrosymmetric rings consisting of two cations and two anions are formed, with the components linked by alternating O-H⋯O and N-H⋯O hydrogen bonds. Short O⋯Br contacts [3.243 (2) and 3.359 (2) Å] may help to consolidate the packing.

4-Cyano-1-methyl-pyridinium iodide.

Project description:In the crystal structure of the title compound, C(7)H(7)N(2) (+)·I(-), the cations form inversion-related dimers via weak pairwise C-H⋯N hydrogen bonds. In the dimers, the pyridinium rings are parallel to one another with their mean planes separated by a normal distance of ca 0.28 Å. Weak C-H⋯N inter-actions between adjacent dimers generate a layer lying parallel to (10-1). The remaining H atoms form C-H⋯I inter-actions, which link the layers into a three-dimensional structure.

2-Cyano-1-methyl-pyridinium iodide.

Project description:The cation in the title compound, C7H7N2 (+)·I(-), is planar (r.m.s. deviation for the nine fitted non-H atoms = 0.040 Å). The crystal packing is best described as undulating layers of cations and anions associated via C-H⋯I inter-actions.

1-(4-Methyl-benzyl-ideneamino)pyridinium iodide.

Project description:The title compound, C(13)H(13)N(2) (+)·I(-), is a derivative of 1-amino-pyridinium iodide. The pyridine and benzene rings are oriented at a dihedral angle of 45.78 (3)°. In the crystal structure, weak inter-molecular C-H⋯I hydrogen bonds link the mol-ecules.

4-(2-Carb-oxy-vin-yl)pyridinium iodide.

Project description:In the crystal structure of the title salt, C(8)H(8)NO(2) (+)·I(-), the cations and anions are linked by bifurcated N-H?(O,I) hydrogen bonds. A near-linear O-H?I hydrogen bond also exists between the cation and anion, resulting in a two-dimensional network. In the cation, the carboxyl group is twisted with respect to the pyridine ring at a dihedral angle of 15.34?(17)°.

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.

2-Oxo-2,3-dihydro-1H-imidazo[1,2-a]pyridinium iodide.

Project description:In the title compound, C(7)H(7)N(2)O(+)·I(-), the carbonyl C and O atoms of the cation and the iodide ion are situated on mirror planes. The mean plane of the imidazo[1,2-d]pyridinium cation is perpendicular to the mirror plane as a consequence of the disorder of the cation over two opposite orientations of equal occupancy. In the crystal, N-H?I interactions are present.
