Chemical bonding


Chemical bonding refers to the attraction between atoms and can come in several different types with varying strength. It allows the formation of substances with more than one atomic component and is the result of the electromagnetic force between opposing charges. Understanding the making and breaking of bonds is at the heart of chemistry.

    X-ray and neutron diffraction studies, in conjunction with quantum chemical techniques, have been used to define a new oxidative bond activation pathway that involves simultaneous activation of both bonds of a β-diketiminate-stabilized GaH2 unit at a single metal centre.

    The field of high-valent uranium chemistry has been dominated by the linear uranyl moiety [UO2]2+ and its imido analogues. A family of tetrakis(imido)uranate dianions has now been developed that displays four uranium–nitrogen multiple bonds. Their geometry is dictated by cation coordination and steric factors rather than electronic ones.

    Berkelium is the only transplutonium element predicted to be able to exhibit both +III and +IV oxidation states in solution. Bk(IV) has now been stabilized through chelation with a siderophore derivative. The resulting neutral coordination compound was characterized and compared with the negatively charged species obtained by chelation of neighbouring trivalent actinides.

    Understanding the interplay between electronic structure and performance and how it relates to mechanism is important for catalysis. Here the authors report an asymmetric [3+2] cycloaddition and show the Ni(II) catalyst possesses a weakly bound acetate ligand, leaving the dz2 orbital partially vacant.

    The relative inertness of dinitrogen can be overcome by coordination to suitable organometallics. This Review explores the influence of coordination mode on the likelihood of functionalization and the nature of the products, which take the form of nitrogen-containing complexes and organics, as well as species such as NH3 and N2H4.
