Journal ArticleDOI
Molecular single-bond covalent radii for elements 1-118.
Pekka Pyykkö,Michiko Atsumi +1 more
TL;DR: A self-consistent system of additive covalent radii, R(AB)=r(A) + r(B), is set up for the entire periodic table, Groups 1-18, Z=1-118, and is close to the methyl-based one of Suresh and Koga and its predecessors.
Journal ArticleDOI
Molecular Double-Bond Covalent Radii for Elements Li–E112
Pekka Pyykkö,Michiko Atsumi +1 more
TL;DR: The previous systems of triple-b Bond and single-bond self-consistent, additive covalent radii, R(AB)=r(A)+ r(B), are completed with a fit for sigma(2)pi(2).
Journal ArticleDOI
Molecular tweezers for hydrogen: synthesis, characterization, and reactivity.
Victor Sumerin,Felix Schulz,Michiko Atsumi,Cong Wang,Martin Nieger,Markku Leskelä,Timo Repo,Pekka Pyykkö,Bernhard Rieger +8 more
TL;DR: The first ansa-aminoborane N-TMPN-CH2C6H4B(C6F5)2 which is able to reversibly activate H2 through an intramolecular mechanism is synthesized and is employed in the catalytic reduction of nonsterically demanding imines and enamines under mild conditions to give the corresponding amines in high yields.
Journal ArticleDOI
Experimental and theoretical treatment of hydrogen splitting and storage in boron–nitrogen systems
Victor Sumerin,Felix Schulz,Martin Nieger,Michiko Atsumi,Cong Wang,Markku Leskelä,Pekka Pyykkö,Timo Repo,Bernhard Rieger +8 more
TL;DR: In this article, the authors review the recent literature on cases where the split H2 forms an N-H⋯H-B dihydrogen bond and show that the di-hydrogen interaction is the key actor in the hydrogen liberating process.
Journal ArticleDOI
Molecular hydrogen tweezers: structure and mechanisms by neutron diffraction, NMR, and deuterium labeling studies in solid and solution.
Felix Schulz,Victor Sumerin,Sami Heikkinen,Bjoern Pedersen,Cong Wang,Michiko Atsumi,Markku Leskelä,Timo Repo,Pekka Pyykkö,Winfried Petry,Bernhard Rieger +10 more
TL;DR: The mechanism of reversible hydrogen activation by ansa-aminoboranes, 1-N-TMPH-CH(2)-2-[HB(C( 6)F(5))(2)]C(6)H(4) (NHHB), was studied by neutron diffraction and thermogravimetric mass-spectroscopic experiments in the solid state as well as with NMR and FT-IR spectroscopy in solution.
