Samenvatting
In recent years gas-phase chemical studies assisted by physical
pre-separation allowed for the investigation of fragile single molecular
species by gas-phase chromatography. The latest success with the
heaviest group 6 transactinide seaborgium is highlighted. The formation
of a very volatile hexacarbonyl compound Sg(CO)6 was observed
similarly to its lighter homologues molybdenum and tungsten. The
interactions of these gaseous carbonyl complex compounds with quartz
surfaces were investigated by thermochromatography. Second-generation
experiments are under way to investigate the intramolecular bond between
the central metal atom of the complexes and the ligands addressing the
influence of relativistic effects in the heaviest compounds. Our
contribution comprises some aspects of the ongoing challenging
experiments as well as an outlook towards other interesting compounds
related to volatile complex compounds in the gas phase.
