In two recent combined experimental and computational studies, the optimal cage for each endohedral metallofullerene within the families Ti@C2n and Ca@C2n has been identified and key aspects of the intriguing growth mechanisms of fullerenes were unravelled....
Highlights with ‘bonding analysis’
Resonance-Assisted Halogen Bonds in N-Halo-Guanine Quartets
Due to cooperative effects, the total hydrogen-bond energy in guanine quartets is more stabilizing than four times the bond energy of a single guanine pair (see previous highlight). Based upon the similar bonding mechanism of...
Structural and electronic properties of uranium-encapsulated Au14
Gold nanoclusters have a good biocompatibility and low cytotoxicity. Encapsulated metal atoms can stabilize gold nanoclusters as well as change chemical and physical properties with respect to hollow clusters. Based on a typical Au14-cage structure, Prof. Wang...
Reactive cluster model of metallic glasses
Metallic glasses are still poorly understood, especially the lack of long-range order. In a bottom-up approach, researchers from the Colorado School of Mines have studied the chemical interactions between clusters underlying the acrystalline behavior of...
Uranyl nanocapsules: structure & stability
A combined experimental and theoretical exploration of uranyl nanoclusters is the recent cover piece of Chem. Eur. J. Uranyl polyoxometalates from 28 units (U28) form nanocapsules that are stabilized by the anion they encapsulate. In this study...
Gold-Carbon Bonding in Gold-Alkynyl Complexes
Researchers from Brown University and Tsinghua University investigated and analyzed the chemical bonding between gold and carbon in gold-alkynyl complexes combining photoelectron spectroscopy and relativistic quantum chemical calculations. The importance of this work for understanding...
Stable GaX2, InX2 and TlX2 radicals
Group 13 M(II) species are very rare and unstable, yet may well be key electron transfer intermediates. Employing bulky boryl ligands, thermally stable M(boryl)2 complexes (M=Ga,In,Tl) have been isolated and characterized for the first time....
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...
