Structural data pertaining to bimetallic complexes with semibridging carbonyl (SBCO) ligands are analyzed using a comprehensive search of the Cambridge Structural Database (CSD). A brief review of the history of SBCO structures is presented, and this history is evaluated in light of the vastly larger dataset available today from the CSD. Additionally, computational analysis is used to reinforce...

Conjugate addition of organometallic reagents to enones to form silyl enol ether products is a versatile method to difunctionalize activated olefins, but the organometallic reagents required can be limiting. The reductive cross-electrophile coupling of unhindered primary alkyl bromides with enones and chlorosilanes to form silyl enol ether products is catalyzed by a nickel-complexed ortho-bromi...

The past several years has witnessed a surge of interest in organometallic trihalide perovskites, which are at the heart of the new generation of solid-state solar cells. Here, we calculated the static conductivity of charged domain walls in n- and p- doped organometallic uniaxial ferroelectric semiconductor perovskite CH3NH3PbI3 using the Landau-Ginzburg-Devonshire (LGD) theory. We find that d...

In this paper, we show that the ambiphilic properties of some organic ligands in organometallic complexes may be retrieved readily from simple calculations in the framework of conceptual density functional theory (C-DFT): namely, the dual descriptor (DD) and the molecular electrostatic potential (MEP) of the ligands afford a rather straightforward interpretation of experimental trends such as t...

Organometallic complexes have unique physico-chemical properties, which have been widely used in homogenous catalysis, for example, for the synthesis of lead compounds and drug candidates. Over the past two decades, a few scientists from all over the world have extended the use of the specific characteristics of these compounds (e.g. structural diversity, possibility of ligand exchange, redox a...

The solubility and solubility trends of organometallic complexes in supercritical carbon dioxide are reviewed. The influence of intermolecular forces, physical properties and the metal chelates on solubility is explored. A number of thermodynamic models used to predict the solubility behavior of organometallic complexes in supercritical carbon dioxide, and the advantages and limitations to thes...

Intermetallics (M1/M2) of abundant metals very different properties can substitute rare and precious for industrial catalysis. A challenge in this context is the atom-precise -efficient catalyst design at size regime ≤ 1 nm, where every metal atom counts. Along these lines thought we have been developing a novel way to generate libraries all-hydrocarbon (R*) ligated clusters [M1aM1b](R*)c. Thes...
