Area of Science:

• Organic Chemistry
• Crystallography
• Molecular Structure

Background:

• Understanding the conformational preferences and intermolecular interactions of heterocyclic compounds is crucial in organic chemistry.
• Benzoyl-pyridine and hexahydropyrimidine are key building blocks for novel nitrogen-containing heterocycles.

Purpose of the Study:

• To synthesize and characterize a new compound formed from benzoyl-pyridine and hexahydropyrimidine.
• To elucidate the three-dimensional structure, including ring conformation and hydrogen bonding patterns, of the synthesized molecule.

Main Methods:

• Chemical synthesis involving the reaction of benzoyl-pyridine with hexahydropyrimidine.
• X-ray crystallography or similar techniques to determine the solid-state structure.
• Analysis of bond lengths, angles, and non-bonded interactions.

Main Results:

• The title compound, C(15)H(17)N(3), was successfully synthesized.
• The 1,3-diazinane ring adopted a chair conformation.
• Weak intramolecular and intermolecular hydrogen bonds were identified, involving N-H groups and the pyridine nitrogen.
• The phenyl and pyridine rings exhibited specific orientations (equatorial and axial, respectively) relative to the diazinane ring.

Conclusions:

• The study provides detailed structural insights into a novel heterocyclic compound.
• The observed hydrogen bonding and conformational preferences are key features of this molecular architecture.
• This research contributes to the understanding of structure-property relationships in nitrogen-containing heterocycles.
