Polar Metallocenes [PDF]

Molecules, 2019
Crystalline polar metallocenes are potentially useful active materials as piezoelectrics, ferroelectrics, and multiferroics. Within density functional theory (DFT), we computed structural properties, energy differences for various phases, molecular ...

Catalytic Undirected Meta‐Selective C–H Borylation of Metallocenes [PDF]

Advanced Science, 2023
Metallocenes are privileged backbones in the fields of synthetic chemistry, catalysis, polymer science, etc. Direct C–H functionalization is undoubtedly the simplest approach for tuning the properties of metallocenes.

Synthesis and characterization of a formal 21-electron cobaltocene derivative [PDF]

Nature Communications, 2023
Metallocenes are highly versatile organometallic compounds. The versatility of the metallocenes stems from their ability to stabilize a wide range of formal electron counts.

Group 8 metallocenes as single-source precursors for the synthesis of light-element-stabilized FCC phases under extreme conditions [PDF]

Science and Technology of Advanced Materials
Metallocenes are promising single-source precursors for the synthesis of transition-metal carbides and hydrides due to their atomic-scale mixing of metal, carbon, and hydrogen. In this study, we investigated the high-pressure and high-temperature (HP–HT)

Adsorption of Metallocenes on Silica

Chemistry - A European Journal, 2016
AbstractThe adsorption of the metallocenes ferrocene, doubly deuterated ferrocene, cymantrene and nickelocene, as well as molybdenum hexacarbonyl, proceeds in the absence of a solvent. Large single pieces of silica gel were placed in contact with the solid metallocenes and the adsorption process was visualized on a macroscopic scale and the maximal ...

Coexistence of Metallocene Cations and Anions. [PDF]

J Am Chem Soc
We report the synthesis and structural characterization of the rhodocene anion [Rh(C5Me5)(C5(CF3)5)]− [1]− as the [Co(C5Me5)2]+ salt, representing an unprecedented coexistence of metallocene cations and anions in different oxidation states. [Co(C5Me5)2]+ [1]− was synthesized by the reduction of the rhodocenium cation [Rh(C5Me5)(C5(CF3)5)][BF4] ([1 ...

Trends in actinide electronic structure revealed from asymmetric, isostructural transuranic metallocenes [PDF]

Communications Chemistry
The study of actinide electronic structure and bonding within rigorously controlled environments is fundamental to advancing nuclear applications. Here, we report a new set of isostructural actinide organometallics; An(COTbig)2, (An = Th, U, Np, and Pu),
