Understanding Band Structures – “Mirrors of Bonding” in Perovskite Crystals

Band structures are a widely used tool in solid state physics and materials science to analyze the electronic structure of crystalline materials. However, the band structure of materials relevant for actual applications are often rather...

Perovskite Band Structure & COOP Analysis – Advanced Tutorial

Whether you are a solid state physicist thinking of chemistry as too arcane or a chemist puzzled by band structure theory: Try out our new tutorial and learn how to neatly link these two fields,...

NMR – NBO analysis tutorial

Check out the new ADF advanced tutorial on analyzing NMR chemical shifts with NBOs. As established in a 2017 paper by Jochen Autschbach et al., the chemical shifts due to substitutions on an aromatic ring...

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...
