Conclusion
The crystal structure of the compound shows a distorted tetrahedral coordination of the mercury atom with stabilizing π–π interactions between adjacent pyridine rings.
Supporting Evidence
- The mercury atom is coordinated by two pyridine N atoms and two bromide anions.
- The centroid-centroid distance between adjacent pyridine rings is 3.648 Å.
- The crystal structure was stabilized by π–π interactions.
Takeaway
Scientists studied a special crystal made of mercury and pyridine, and they found that the mercury is surrounded by other atoms in a unique shape that helps hold the crystal together.
Methodology
The crystal structure was determined using single-crystal X-ray diffraction methods.
