Summary
This study details the crystal structure of a novel organic salt, C(18)H(26)N(2) (2+)·2Br(-)·2H(2)O. Hydrogen bonds between cations, anions, and water molecules form an intricate three-dimensional framework.
Area of Science:
- Crystallography
- Supramolecular Chemistry
Background:
- Understanding the self-assembly of organic molecules is crucial in materials science.
- Crystal engineering aims to design materials with specific properties based on intermolecular interactions.
Purpose of the Study:
- To elucidate the crystal structure of the organic salt C(18)H(26)N(2) (2+)·2Br(-)·2H(2)O.
- To investigate the intermolecular interactions, including hydrogen bonding, that govern the crystal packing.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, and intermolecular contacts was performed.
Main Results:
- The asymmetric unit contains half an organic cation, a bromide anion, and a water molecule.
- The organic cation lies on a center of inversion, with a dihedral angle of 59.3° between the pyridine ring and the central linkage.
- A three-dimensional framework is formed through O-H⋯Br, C-H⋯Br, and C-H⋯O hydrogen bonds.
Conclusions:
- The crystal structure reveals a well-defined three-dimensional network stabilized by multiple hydrogen bonding interactions.
- This structural information provides insights into the supramolecular assembly of organic salts and their potential applications.

Electrophilic 1,2- and 1,4-Addition of X2 to 1,3-Butadiene
Electrophilic addition of halogens to alkenes proceeds via a cyclic halonium ion to form a 1,2-dihalide or a vicinal dihalide.
Structure of Conjugated Dienes
Introduction
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction
The Diels–Alder reaction is an example of a thermal pericyclic reaction between a conjugated diene and an alkene or alkyne, commonly referred to as a dienophile. The reaction involves a concerted movement of six π electrons, four from the diene and two from the dienophile, forming an unsaturated six-membered ring. As a result, these reactions are classified as [4+2] cycloadditions.
Electrophilic 1,2- and 1,4-Addition of HX to 1,3-Butadiene
The electrophilic addition of hydrogen halides such as HBr to alkenes and nonconjugated dienes gives a single product as per Markovnikov’s rule.
π Molecular Orbitals of 1,3-Butadiene
Conjugated dienes have lower heats of hydrogenation than cumulated and isolated dienes, making them more stable. The enhanced stabilization of conjugated systems can be understood from their π molecular orbitals.
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...

Aromatic Hydrocarbon Cations: Structural Overview
Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.
