About this collection
Tin: Modern chemistry of an element from antiquity
This collection of articles in Dalton Transactions focuses on the inorganic, metalorganic and organometallic chemistry of the heavier Group 14 element, tin. As an element, tin has been exploited by humanity for over 5000 years, since it was realised that its alloy with copper provided an even more durable material, bronze. In more recent times, and throughout the half century of Dalton Trans., tin has played, and continues to occupy, a central role in the development of many of our current perspectives on the bonding and application of the whole gamut of main group element chemistry.
Guest edited by Mike Hill (University of Bath) and John McGrady (University of Oxford), this collection of reports reflects our prevailing interest in an element that has played a central role not only in the development of modern chemistry but in human history. Both of the commonly accessible (II) and (IV) oxidation states are represented by this compendium of reports, which span fundamental studies of bonding and structure to emerging applications in small molecule activation, catalysis and materials science.
Articles will be added to this themed collection as soon as possible after they are published. Please return to this page frequently to see the collection grow.
