Conclusion
The structure of the compound was redetermined at a lower temperature, revealing significant differences in unit-cell dimensions and density compared to previous measurements.
Supporting Evidence
- The redetermined structure showed a c-axis length of 13.8401 (8) Å, which is significantly different from the previous report.
- The density of the compound was found to be 1.309 g cm-3, contrasting with earlier findings.
- Improved precision in the structure determination was achieved using Mo Kα radiation.
Takeaway
Scientists looked at a chemical compound again at a colder temperature and found it looked different than before.
Methodology
The structure was determined using low-temperature X-ray diffraction with Mo Kα radiation.
Limitations
The study only focused on the redetermination of the structure at one temperature and did not explore other conditions.
