Conclusion
The study reports a new triclinic polymorph of an iron-sulfur compound, which differs in structure from a previously known monoclinic form.
Supporting Evidence
- The new triclinic polymorph is the second known form of this composition.
- The structure features an Fe2S2 core with a butterfly-like shape.
- The crystal packing is stabilized by van der Waals interactions.
Takeaway
Scientists discovered a new version of a compound made of iron and sulfur, which has a different shape than one they found before.
Methodology
The compound was synthesized under nitrogen atmosphere using standard Schlenk techniques and characterized using X-ray crystallography.
Limitations
The yield of the new compound was low and variable, less than 5%.
