Seaborgium hexacarbonyl (also called seaborgium carbonyl) is the organometallic compound with the formula Sg(CO)6. Like its chromium, molybdenum, and tungsten analogs, it is a volatile derivative of seaborgium in its zero oxidation state.[1] Seaborgium hexacarbonyl has little practical usage, outside of scientific interest, where it and other transactinide compounds are studied to shed light on relativistic effects on electronic structure as a consequence of high nuclear charge.
Synthesis
[edit ]Sg(CO)6 can be prepared by passing seaborgium atoms through a helium and carbon monoxide mixture:[1]
- Sg + 6 CO → Sg(CO)6
Reactivity
[edit ]Seaborgium hexacarbonyl reacts and interacts with a SiO2 surface in ways closely resembling its lighter congeners, molybdenum hexacarbonyl and tungsten hexacarbonyl.[1]
