Chemical bonding

Definition

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.

    Metal complexes of the pentazole anion exhibit multiple coordination modes, through ionic, covalent and hydrogen-bonding interactions, and good thermal stability with onset decomposition temperatures greater than 100 °C.

    Interest in surface-mediated chemistry has led to the design of small molecule models for surfaces, which provide mechanistic insight and have practical applications. Now, the cooperative behaviour of five nickel centres has been shown to provide reactivity reminiscent of highly active metal surface sites, leading to carbon-atom abstraction from alkenes under ambient conditions.

    Mononuclear gold(II) complexes are very labile (and thus very rare) species. Now, a gold(II) porphyrin complex has been isolated and characterized, and its reactivity towards dioxygen, nitrosobenzene and acids investigated. Owing to a second-order Jahn–Teller distortion, the gold atoms were found to adopt a 2+2 coordination mode in a planar N4 environment.

    Bis(β-diketiminato)dimagnesium(I) complexes are low-valent reagents that can each deliver two electrons in a selective and stoichiometric manner. Easily handled and dissolved, these species effect reduction of many inorganic and unsaturated organic substrates. This Perspective covers the development of magnesium(I) dimers and the scope of their reactivity.

    Single molecule magnets have demonstrated promise for information storage, molecular spintronics and quantum computing, but are limited by their low operational temperatures. Here, Popov and coworkers prepare a SMM with a high blocking temperature of 18 K by trapping two lanthanide ions with a single-electron bond inside a fullerene.
