Coordination chemistry

Coordination chemistry is the study of compounds that have a central atom (often metallic) surrounded by molecules or anions, known as ligands. The ligands are attached to the central atom by dative bonds, also known as coordinate bonds, in which both electrons in the bond are supplied by the same atom on the ligand.

    Octa-coordinated complexes or ions have a bond order of seven, yet they accommodate eight lone-pairs of ligands. Here the Jellium model is demonstrated to be an appropriate description of the valence bonding structures of M(CO)8 species, where each coordinative bond contains 7/8ths of the bonding orbitals and 1/8th non-bonding orbitals.

    Metal-ligand δ and φ interactions, though considered weak, may be necessary for fully describing the electronic and geometric structures of certain compounds. Here, in actinide metallacycles, the authors discover two new types of M-L δ and φ back-bonds that contribute substantially to their unusual chemical behavior.

    Electron spin is a fundamental property of molecules, and changes in spin state affect both molecular structure and dynamics. Here, the authors resolve, by ultrafast electron diffraction, the nuclear reorganization stabilizing spin transitions in a [FeII(bpy)3](PF6)2 crystal.

    Strong spin-spin interactions between surface-deposited magnetic molecules are desirable for quantum computing applications. Here the authors use scanning tunneling microscopy and spectroscopy to investigate the spin-spin interactions between neighbouring porphyrazine-derivatives on Au(111).

    Lanthanoid complexes are widely used for various applications but so far it is difficult to combine multiple lanthanoids into one single molecular entity with sufficient stability. Here, the authors report a method for this purpose using peptide synthesis, and show that a trinuclear lanthanoid complex can be used to create a luminescence nanocode.

    Transition metal-catalysed C–H hydroxylation is one of the most notable synthetic advances to access alcohols and phenols. Here, the authors report a metal-free, mild C–H hydroxylation of (hetero)arenes via boron-mediated chelation.
