Chemical bonding
In this collection we explore the fundamental principles of chemical bonding, covering covalent, ionic, and metallic bonding, as well as molecular structure, intermolecular forces, and the role of chemical bonding in shaping the properties and behaviour of molecules.
Highlights
The mechanical side of bonding
Synthetic chemists are finally mastering the assembly of interlocked molecules held together by the mechanical bond, find James Mitchell Crow
Reaching into the non-covalent toolbox
Alongside supramolecular stalwarts, budding bonding forms are vying to be valuable, finds Andy Extance
When a bond gets too extreme
Chemical bonds are part of the way chemists rationalise the behaviour of atoms in the conditions of the world around them. Tim Wogan looks at how they are affected when those conditions change

Do bond classifications help or hinder chemistry?
Ionic, covalent, metallic and more… but there’s debate about whether bonds are real at all
The forgotten female crystallographer who discovered C–H⋯O bonds
Andy Extance tells the overlooked story of crystallographer June Sutor, whose C–H⋯O bonding hypothesis was unjustly suppressed
