This study reveals the chair conformation of a hexa-hydro-pyrimidine ring in a novel compound. Intermolecular hydrogen bonding forms helical chains within the crystal structure.
Area of Science:
- Crystallography
- Organic Chemistry
- Materials Science
Background:
- Understanding the three-dimensional structure of organic compounds is crucial for predicting their properties and reactivity.
- Hexa-hydro-pyrimidine derivatives are important scaffolds in medicinal chemistry and materials science.
- Detailed structural analysis provides insights into intermolecular interactions and crystal packing.
Purpose of the Study:
- To elucidate the crystal structure and molecular conformation of the title compound, C(10)H(15)N(3).
- To investigate the nature of intermolecular interactions, specifically hydrogen bonding, within the crystal lattice.
- To describe the resulting supramolecular architecture formed by these interactions.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the precise atomic arrangement.
- Analysis of bond lengths, bond angles, and conformational parameters described the molecular geometry.
- Intermolecular interactions, including hydrogen bonds, were identified and characterized.
Main Results:
- The hexa-hydro-pyrimidine ring adopts a chair conformation, with pyramidally coordinated nitrogen atoms.
- A significant intermolecular hydrogen bond was observed between an amido -NH group and a pyridyl nitrogen atom.
- These hydrogen bonds link molecules into a helical chain structure along the b axis of the ortho-rhom-bic unit cell.
Conclusions:
- The study provides a detailed structural characterization of the title compound.
- The observed helical chain formation highlights the role of specific intermolecular interactions in directing crystal packing.
- This structural insight can inform the design of new materials with tailored properties.

Criteria for Aromaticity and the Hückel 4n + 2 Rule
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n + 2 rule.
Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
