Seaborgium hexacarbonyl (also called seaborgium carbonyl) is the organometallic compound (a metal carbonyl) 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

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

Seaborgium hexacarbonyl reacts and interacts with a SiO₂ surface in ways closely resembling its lighter structural analogs, molybdenum hexacarbonyl and tungsten hexacarbonyl. ^[1]
