Highlights with ‘bonding analysis’

Main Group Elements as Transition Metals: Alkaline Earth Octacarbonyls with 18-electrons

Generally, main group elements prefer obeying the 8-electron rule; while the transition metal elements tend to follow the 18-electron rule. Recently, scientists reported the isolation and spectroscopic identification of the eight-coordinated alkaline earth carbonyl complexes...

Facile Arylic C–X Bond Activation Explained

In their recent publication in Scientific Reports, Vermeeren, Sun, and Bickelhaupt for the first time reveal the physical origin of why metal-mediated activation of arylic C–X bonds is more facile than that of the corresponding...

Novel Thorium Arsenic Multiple Bonds

A recent Nature Communication paper reports thorium complexes with Th-As multiple bonds, stabilized by bulky triamidoamine ligands. The bonding interactions in the novel thorium arsinidiides (ThAs(H)K and ThAs(H)Th) and arsenido (ThAsTh) are studied with relativistic...

Covalent Bonding in Heavy Actinides

The separation of highly radioactive minor actinides from lanthanides and other fission products within the nuclear fuel cycle is crucial in both the recycling of used nuclear fuel and as a prelude to waste storage....

5f covalency in Americium hexachloride

The Cl K-edge XAS of Americium(III) Hexachloride were simulated and analyzed based on spin-orbit DFT transition dipole moment method. Direct evidence of 5f and 3p orbital mixing in Am–Cl bond was observed. Combining experimental Cl K-edge XAS and theoretical simulation, the comparison between AmCl63-...

8-coordinated fluoride inside a zeolite

The intriguing bonding interactions of fluoride inside a silicate double 4-ring (D4R) – a common zeolite unit- have been scrutinized with ADF in a recent paper by Goesten, Hoffmann, Bickelhaupt, and Hensen. As now theoretically shown, all halides prefer...

Promoters in Fischer-Tropsch catalysis

The Fischer-Tropsch reaction aims at synthesizing lower olefins (C2-C4 alkenes) from synthesis gas (CO + H2). In this reaction, typically large amounts of methane are formed as an unwanted side product. In a combined experimental and theoretical study, computational...

Periodic energy decomposition analysis

A periodic extension of the energy decomposition analysis (pEDA) has been implemented in BAND. The natural orbitals for chemical valence (NOCV) is also available – at the gamma-point only. With pEDA researchers can analyze in...

Efficiency of Ru dyes in DSSCs

The performance of seven ruthenium dyes in DSSC devices was predicted employing a molecular model were the dye is linked to two Ti(OH)3 units. The theoretical efficiency of the dyes is determined by three factors: 1) the amount of...
