5-Nitro-2,3-bis-(thio-phen-2-yl)quinoxaline

Area of Science:

• Organic Chemistry
• Crystallography
• Materials Science

Background:

• Quinoxaline derivatives are important scaffolds in medicinal chemistry and materials science.
• Understanding the three-dimensional structure of novel organic compounds is crucial for predicting their properties and applications.

Purpose of the Study:

• To synthesize a new compound containing quinoxaline and thienyl moieties.
• To determine the solid-state structure and conformation of the synthesized compound using X-ray crystallography.

Main Methods:

• Synthesis of the title compound (C16H9N3O2S2) via a condensation reaction.
• Recrystallization from acetic acid.
• Single-crystal X-ray diffraction analysis to determine molecular structure and crystal packing.

Main Results:

• The title compound was successfully synthesized and characterized.
• X-ray diffraction data revealed the crystal structure.
• The dihedral angles between the quinoxaline mean plane and the thienyl rings were determined to be 35.16(5)° and 24.94(3)°, indicating significant deviation from planarity.

Conclusions:

• A novel C16H9N3O2S2 compound featuring quinoxaline and thienyl groups was synthesized.
• The compound exhibits a non-planar conformation in the solid state, with defined dihedral angles between the ring systems.
• These structural findings provide a basis for further investigation into the compound's potential applications.
