It is now well-known that (2)H solid-state NMR techniques can bring a better understanding of the interaction of deuterium with metal atoms in organometallic mononuclear complexes, clusters or nanoparticles. In that context, we have recently obtained experimental quadrupolar coupling constants and asymmetry parameters characteristic of deuterium atoms involved in various bonding situations in r...

Three closely related organometallic "spoke-wheel" complexes featuring coinage metal ions, Au(I), Ag(I), and Cu(I), bonded to three norbornene molecules in trigonal planar fashion have been isolated and completely characterized using several methods including X-ray crystallography.

A straightforward, reduction-free method for the synthesis of organometallic cobalamins has been developed. Stable phenylacetylide derivatives were characterized by X-ray analysis, showing a pronounced influence of the electronic nature of substituents on their structure.

Thermally-reversible covalent polymers featuring dynamic carbon-carbon double bonds and tunable molecular weights were prepared from difunctional carbenes; addition of transition metal complexes to these materials afforded the respective main-chain organometallic polymers.

A chiral-at-metal Ir(III) organometallic metallatecton was synthesised as a racemic mixture and as enantiopure complexes and combined with Cu(II) to afford a heterobimetallic (Ir,Cu) grid-type 2D coordination network.

[structure: see text] A highly convergent synthesis of the proposed structure of amphidinolide A is reported. Instructive applications of several organometallic processes are illustrated, including a highly selective ring-closing metathesis reaction.
