Highlights with ‘bonding analysis’

Singlet Fission Yields in Organic Crystals

The splitting of a singlet excited state in two triplet excited states, singlet fission (SF), could drastically enhance the efficiency of organic photovoltaic (OPV) devices. In practice, however, the SF yield is typically very low....

Nonlinear (d)10 dicoordinated transition metal complexes

In a cover-featured article, Lando Wolters and Matthias Bickelhaupt have analyzed the bonding mechanism in a series of d10 transition metal complexes ML2 with ADF. There is a subtle interplay between interligand steric (Pauli) repulsion...

Unraveling f-block bonding interactions: novel uranium complexes

In a series of break-through papers, Prof. Steve Liddle and his collaborators report the synthesis, isolation, and characterization of new uranium complexes. In a sustained, exciting effort to establish and understand novel chemical bonds in...

Agostic Isomers: different colors and structures

Researchers from PNNL have, for the first time, isolated and characterized two agostic isomers (‘agostomers’). Isomers of a cationic Mo piano stool complex, important intermediates in catalytic hydrogenation, have been separated by crystallization and can...

Insights in Mo (di)hydride bonds with ETS-NOCV

Bonding interactions in non-classical hydride/dihydrogen molybdocenes and their interconversion to trihydrides have been analyzed with ETS-NOCV in a recent inside-cover featured article. Ansa-bridges with a small bite angle make the Mo center more sterically available, favoring the...

Stable Aminyl Radical Metal Complex supported by ADF EPR calculations

Chemistry & Engineering News (January 17, 2005 issue, page 34) reports about the recent Science paper Science, vol. 307, p.235 (2005) by a team of the ETH Zurich, led by Prof. Grützmacher. The team has...

Slaters beat Gaussians for Fe-complexes

In a recent paper, J. Phys. Chem. A, 112 (28), p. 6384, 2008, Güell, Luis, Sola, and Swart, compare ADF’s Slater Type Orbital (STO) basis sets to Gaussian Type Orbitals (GTO) basis sets in a...

The First Dodecavalent Molybdenum Complex studied with ADF

Recently Prof. Gernot Frenking’s group in Marburg, Germany was involved in a joint experimental – theoretical paper that reported the synthesis and characterization of a unique molybdenum – zinc complex in which the zinc atoms...

Lithium – Ammonia solution modeled at the molecular level

In a recent edition of Angewandte Chemie, Eva Zurek, now at the University at Buffalo, along with Peter P. Edwards at the University of Oxford and Roald Hoffmann at Cornell University published a detailed computational...

Catalyst selection: survival of the weakest

ADF calculations support a new mass spectrometric method to select the best catalysts from a combinatorial library in a combined experimental-theoretical study. The turnover frequency determining step for the Pd-catalyzed allylic alkylation is the nucleophilic...
