A lanthanide–carbon triple bond has been created for the first time, specifically a bond between cerium and carbon, ...

Deep-seated and shielded by the outer 5s and 5p orbitals, the 4f orbitals lie close to the atomic nucleus, making it difficult for them to overlap with orbitals of other atoms and form chemical bonds.

While scientists have developed computational approaches to describe how covalent or ionic a bond is, experimentally measuring how the orbital character of electrons or the changes in covalency ...

Now chemists have brought out a surprising extrovert streak in the orbitals, in what they believe is the first clear example of 4f bonding actually steering the course of a reaction (Nat. Chem ...

Theory predicts that the bond in this material is much more covalent than typical iron-oxygen bonds, which tend to be quite ionic in most iron-containing compounds. Using the x-ray reflectivity ...
