Introduction	Studying transactinide elements offers crucial data for chemical theory and assesses periodic table trends. Previously, gas-phase chemical reactions yielded simple inorganic compounds of transactinides in their highest oxidation states. However, low single-atom production rates, brief half-lives, and challenging experimental conditions restricted the range of obtainable compounds. This research utilised a gas-phase carbonylation method, previously validated with short-lived molybdenum (Mo) and tungsten (W) isotopes, to prepare a carbonyl complex of seaborgium (element 106). The resulting volatile seaborgium complex exhibited equivalent volatility and surface reactivity with silicon dioxide as the hexacarbonyl complexes of its lighter counterparts, Mo and W. Analysis of the product's adsorption enthalpy, alongside theoretical projections and data from lighter congeners, affirmed a Sg(CO)6 structure.
