4-(Ammonio-meth-yl)pyridinium dichloride.
This study details the crystal structure of a novel compound, revealing interconnected 4-(ammonio-methyl)pyridinium cations and chloride anions. Hydrogen bonds and π-π stacking interactions dictate the overall crystal packing arrangement.
Area of Science:
- Crystallography
- Materials Science
- Supramolecular Chemistry
Background:
- Understanding the self-assembly of organic molecules is crucial for designing new materials.
- Crystal engineering relies on non-covalent interactions to control solid-state structures.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(6)H(10)N(2) (2+)·2Cl(-).
- To investigate the role of hydrogen bonding and π-π stacking in the crystal packing.
Main Methods:
- Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
- Analysis of intermolecular interactions, including hydrogen bonds and π-π stacking, was performed.
Main Results:
- The crystal structure consists of 4-(ammonio-methyl)pyridinium cations and chloride anions.
- N-H⋯Cl hydrogen bonds form a network connecting the cations and anions.
- Intermolecular π-π stacking interactions between anti-parallel organic cations were observed with a distance of approximately 3.52 Å.
Conclusions:
- The crystal packing is governed by a combination of N-H⋯Cl hydrogen bonds and π-π stacking interactions.
- These interactions lead to a well-defined three-dimensional network structure.
- The findings contribute to the understanding of structure-property relationships in organic salts.

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
