Hypothesis
The study aims to determine the crystal structure of the title compound to enable comparative studies.
Conclusion
The heterocyclic six-membered ring adopts an E2 conformation and the molecules are connected into double layers in the crystal structure.
Supporting Evidence
- The compound was obtained commercially and crystals suitable for X-ray diffraction were taken directly from the provided product.
- The heterocyclic six-membered ring adopts an E2 conformation with carbon atom C1 acting as the envelope-atom.
- C–H···O contacts connect the molecules into double layers perpendicular to the crystallographic a axis.
Takeaway
The researchers looked at how a specific chemical compound is structured, finding that it forms layers in its solid state.
Methodology
X-ray diffraction was used to determine the crystal structure of the compound.
