Metallacarboranes and their interactions: theoretical insights and their applicability† [PDF]

Chemical Society Reviews, 2012
This tutorial review will deal with the study of metallacarboranes and their interactions with other molecules from a theoretical point of view. This contribution is devoted to guide experimental chemists through calculations that some years ago were reserved to theoretical specialists.

Counterion-Induced Aggregation of Metallacarboranes

The Journal of Physical Chemistry C, 2022
The model of counterion-induced metallacarborane aggregation in water was verified on sodium bis(1,2-dicarbollide), one of the most studied examples of metallacarboranes. This case study introduces a novel approach in anionic boron cluster self-assembly that resembles the behavior of polyoxometalate nanoions.

Exploring the Role of Metal in the Biointeraction of Metallacarboranes with C. elegans Embryos

Chemistry - A European Journal, 2023
We have transitioned from performing chemical scale studies involving the interaction of metallabis(dicarbollides) with biomolecules in a round‐bottom flask, to now conducting in vivo experiments using C. elegans. Results suggest metal (Fe or Co) plays a crucial role in C.

Metallacarboranes as Photoredox Catalysts in Water [PDF]

Chemistry – A European Journal, 2020
AbstractMetallacarboranes with the shape of the Greek letter θ, such as [Co(C2B9H11)2]−, were tested, for the first time, as efficient photoredox catalysts in the oxidation of aromatic and aliphatic alcohols in water. Their efficiency is linked to their high solubility in water, their high oxidizing power (Co4+/3+), and their absence of fluorescence on

Metallacarboranes for proton therapy using research accelerators: a pilot study

EPJ Techniques and Instrumentation, 2023
The feasibility of using an external beam microprobe facility to explore the biological effects generated by proton irradiation in cultured cells is demonstrated. An in-air irradiation set-up was developed that allows energy tuning and enables estimating

What Can We Learn from the Crystal Structures of Metallacarboranes?

Crystals, 2017
The determination of the molecular structures of metallacarboranes by X-ray diffraction remains critical to the development of the field, in some cases being the only viable way in which the overall architecture and the isomeric form of the molecule can ...

Patterns in supraicosahedral metallacarboranes [PDF]

, 2013
Chapter one gives an introduction into heteroborane chemistry focussing on supraicosahedral metallacarboranes. Chapter two describes the first examples of untethered 4,1,2-MC2B10 13-vertex metallacarboranes prepared by polyhedral expansion of a tethered
