Carbenes, thought of only as transient species for a long time, have become ubiquitous in
organometallic chemistry. Their interaction with a metal center, which allows for their …

The previous systems of triple‐bond and single‐bond self‐consistent, additive covalent radii,
R (AB)= r (A)+ r (B), are completed with a fit for σ2π2 double‐bonds. The primary bond …

Our first review article in 2006 outlined the observation, photochemical properties, and
theoretical investigations of a new breed of small transition-metal complexes with CM …

A new generation of simple methylidene complexes has been prepared by reactions of
excited group 4− 6 transition metal atoms with methyl halides and methane in solid argon …

The reaction of [AnCl (NR2) 3](An= U, Th, R= SiMe3) with in situ generated lithium-3, 3-
diphenylcyclopropene results in the formation of [{(NR2) 3} An (CHCCPh2)](An= U, 1; Th, 2) …

Reaction of the Th (IV) metallacycle [Th (C H2SiMe2 N SiMe3)(NR2) 2](1; R= SiMe3), with
Ph3P CH2 affords the Th (IV) carbene [Th (CHPPh3)(NR2) 3](2) in good yield. In solution …

The first thorium poly-carbene complexes [(Ph2PS) 2C] 2Th (DME)(2) and [{[(Ph2PS) 2C]
3Th} Li2 (DME)] n (3) have been prepared and structurally characterized. DFT calculations …

Unique in its comprehensive coverage of not only theoretical methods but also applications
in computational spectroscopy, this ready reference and handbook compiles the …

Despite a major expansion of uranium–ligand multiple bond chemistry in recent years,
analogous complexes involving other actinides (An) remain scarce. For thorium, under …

Chemistry of the actinide elements represents a challenging yet vital scientific frontier.
Development of actinide chemistry requires fundamental understanding of the relative roles …
