Superheavy-element compound reveals weaker-than-expected bond due to relativistic effects
An international collaboration led by a research group from GSI/FAIR in Darmstadt, Germany, has achieved the first measurement of the chemical stability of a superheavy element compound.
An international team of researchers from GSI/FAIR in Darmstadt, Germany, has made a significant discovery in the realm of superheavy elements. They have successfully measured the chemical stability of a compound of seaborgium (Sg, element 106), specifically the hexacarbonyl complex Sg(CO)₆. The study reveals that the bond between the seaborgium atom and a carbonyl ligand is weaker than anticipated based on its position in the periodic table.
This phenomenon is attributed to relativistic effects due to the high nuclear charge of superheavy elements. The findings are published in the journal Nature. The study underscores the importance of relativistic effects in altering the electronic structure of superheavy atoms, leading to changes in their chemical properties compared to their lighter counterparts.
