(1-Naphthyl-meth-yl)ammonium chloride.
Researchers studied the reaction between 1-naphthyl-methyl-amine and hydrochloric acid. This reaction formed a proton-transfer compound, C(11)H(12)N(+)·Cl(-), with ions linked by hydrogen bonds in a crystal sheet pattern.
Area of Science:
- Crystallography
- Supramolecular Chemistry
- Organic Chemistry
Background:
- Proton-transfer reactions are fundamental in chemistry.
- Understanding crystal structures reveals intermolecular interactions.
- Naphthylmethylammonium chloride is a specific organic salt.
Purpose of the Study:
- To characterize the proton-transfer compound formed from 1-naphthyl-methyl-amine and hydrochloric acid.
- To investigate the crystal structure and hydrogen bonding of the resulting salt.
Main Methods:
- Reaction of 1-naphthyl-methyl-amine with hydrochloric acid in a 1:1 molar ratio.
- X-ray crystallography to determine the crystal structure.
- Analysis of hydrogen bonding interactions (N-H⋯Cl).
Main Results:
- Formation of a 1:1 proton-transfer compound, identified as C(11)H(12)N(+)·Cl(-).
- The crystal structure exhibits a sheet pattern in the ab plane.
- Ions are linked by N-H⋯Cl hydrogen bonds, with each chloride ion interacting with three ammonium groups.
Conclusions:
- The reaction successfully yielded the naphthylmethylammonium chloride salt.
- The crystal structure demonstrates specific hydrogen bonding patterns crucial for supramolecular assembly.
- This study provides insight into the solid-state behavior of organic proton-transfer compounds.
