A carbonyl compound that tips the scales Life is short for the heaviest elements. They emerge from high-energy nuclear collisions with scant time for detection before they break up into lighter atoms. Even et al. report that even a few seconds is long enough for carbon to bond to the 106th element, seaborgium (see the Perspective by Loveland). The authors used a custom apparatus to direct the freshly made atoms out of the hot collision environment and through a stream of carbon monoxide and… 

Application of a novel gas phase synthesis approach to carbonyl complexes of accelerator-produced 5d transition metals

Abstract In 2014 the first synthesis of a transactinide carbonyl complex – seaborgium hexacarbonyl – was reported. This was achieved in gas-phase chemical experiments in a beam-free environment

Characterization of berkelium(III) dipicolinate and borate compounds in solution and the solid state

The chemistry of Bk, which has proven fiercely challenging to study over the years on account of its vigorous radioactive decay, is revisited and the role of covalent bonding and spin-orbit coupling in determining the electronic properties of berkelium is deconvolute.

The study of rhenium pentacarbonyl complexes using single-atom chemistry in the gas phase.

A gas-phase chemical study of rhenium carbonyls was carried out using short-lived radioisotopes produced at a heavy-ion accelerator and the most stable species was deduced to be Re(CO)5 based on the mass-spectrometric analysis as well as quantum chemistry calculations.

Superheavy carbonyls

It is shown how atoms with atomic numbers Z > 94 can be cooled down and used to synthesize a new class of chemical compounds, the superheavy metal carbonyls, which confirm a 15-year-old prediction of relativistic quantum chemistry.

de Chemistry of the superheavy elements

The quest for superheavy elements (SHEs) is driven by the desire to find and explore one of the extreme limits of existence of matter. These elements exist solely due to their nuclear shell

Decomposition studies of group 6 hexacarbonyl complexes. Part 1: Production and decomposition of Mo(CO)6 and W(CO)6

Abstract Chemical studies of superheavy elements require fast and efficient techniques, due to short half-lives and low production rates of the investigated nuclides. Here, we advocate for using a

Gas-phase chemistry of ruthenium and rhodium carbonyl complexes.

The general chemical behaviors of short-lived carbonyl complexes of group VI-IX elements were discussed, which can be used in the future study on the gas-phase chemistry of superheavy elements - Bh, Hs, and Mt carbonyls.

A test bench is established to challenge the validity and predictive power of modern fully relativistic quantum chemical models and to probe ‘relativistically’ influenced chemical properties and the architecture of the periodic table at its farthest reach.

Studying Chemical Properties of the Heaviest Elements: One Atom at a Time

The search for heavier elements has been an exciting endeavor for nuclear scientists for many decades. This was invigorated after the first predictions that nuclear shell effects might render



Complexes of Carbon Monoxide and Its Relatives: An Organometallic Family Celebrates Its Birthday

Nickel tetracarbonyl was discovered one hundred years ago. Its hundredth birthday deserves to be celebrated not only by metal carbonyl chemists. The pioneering work of Mond, Langer, and Quincke has

In-situ formation, thermal decomposition, and adsorption studies of transition metal carbonyl complexes with short-lived radioisotopes

Abstract We report on the in-situ synthesis of metal carbonyl complexes with short-lived isotopes of transition metals. Complexes of molybdenum, technetium, ruthenium and rhodium were synthesized by

Rapid synthesis of radioactive transition-metal carbonyl complexes at ambient conditions.

Carbonyl complexes of radioactive transition metals can be easily synthesized with high yields by stopping nuclear fission or fusion products in a gas volume containing CO. Here, we focus on Mo, W,


The recent syntheses of several new elements (including the recent reports of elements 116 and 118), coupled with the controversy surrounding the naming of elements 104--109, have stimulated a great

Superheavy element flerovium (element 114) is a volatile metal.

A gas-solid chromatography study of the adsorption of Fl on a Au surface points to the formation of a metal-metal bond of Fl with Au, the least reactive element in the group, but still a metal.

Theoretical predictions of properties and gas-phase chromatography behaviour of carbonyl complexes of group-6 elements Cr, Mo, W, and element 106, Sg.

It is expected that in the future gas-phase chromatography experiments it will be almost impossible--what concerns ΔHads--to distinguish between the W and Sg hexacarbonyls by their deposition on quartz.

Advances in the production and chemistry of the heaviest elements.

This poster presents a probabilistic procedure for determining the response of various materials to Radiochemistry-like properties in the presence of non-volatile organic molecules.
