Summary
This study details the crystal structure of a co-crystal formed by 2,6-diacetyl-pyridine and resorcinol. These molecules self-assemble via hydrogen bonds into planar chains, revealing new insights into crystal engineering.
Area of Science:
- Crystal engineering
- Supramolecular chemistry
- Organic chemistry
Background:
- Co-crystals are crystalline solids composed of two or more different molecular components.
- Understanding intermolecular interactions is key to designing functional materials.
- 2,6-diacetyl-pyridine and resorcinol are organic molecules with potential for hydrogen bonding.
Purpose of the Study:
- To characterize the crystal structure of a novel co-crystal formed between 2,6-diacetyl-pyridine and resorcinol.
- To investigate the intermolecular interactions governing the co-crystal assembly.
- To explore the potential for self-assembly in organic systems.
Main Methods:
- Single-crystal X-ray diffraction was used to determine the molecular and crystal structure.
- Analysis of hydrogen bonding networks and molecular conformations.
- Identification of the asymmetric unit and packing arrangement.
Main Results:
- The co-crystal unit consists of one molecule of 2,6-diacetyl-pyridine and one molecule of resorcinol.
- Two O-H⋯O hydrogen bonds link the 2,6-diacetyl-pyridine and resorcinol molecules.
- These interactions lead to the formation of planar chains of alternating components along the [120] direction.
Conclusions:
- The 2,6-diacetyl-pyridine-resorcinol co-crystal exhibits a well-defined hydrogen-bonding motif.
- The observed chain structure highlights the predictable self-assembly of these organic molecules.
- This structural characterization provides a foundation for further studies in co-crystal design and applications.

01:21[3,3] Sigmatropic Rearrangement of 1,5-Dienes: Cope Rearrangement
The Cope rearrangement is classified as a [3,3] sigmatropic shift in 1,5-dienes, leading to a more stable, isomeric 1,5-diene. The reaction involves a concerted movement of six electrons, four from two π bonds and two from a σ bond, via an energetically favorable chair-like transition state.
01:57Preparation of Diols and Pinacol Rearrangement
Compounds bearing two hydroxyl groups are known as diols. When the hydroxyl groups are located on adjacent carbon atoms, the diols are called vicinal diols or glycols. Under acidic conditions, vicinal diols undergo a specific reaction called pinacol rearrangement.
The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.

02:23Structure and Nomenclature of Alcohols and Phenols
Overview
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.

01:29UV–Vis Spectroscopy: Woodward–Fieser Rules
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a given structure by adding the contributions...
01:34Woodward–Hoffmann Selection Rules and Microscopic Reversibility
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...
