Gold: Inorganic & Coordination Chemistry

Abstract

Gold compounds are finding new applications in catalysis, medicine, and molecular materials, based on their reactivity and unusual physical and chemical properties. The theoretical basis of the unique properties of gold compounds continues to develop rapidly and provides a constant challenge for synthesis of new types of gold compounds. This chapter gives an overview of these exciting developments while giving an overview of the modern inorganic chemistry of gold.

“…While Ru adopts mostly octahedral geometries, Cu or Au show a wide diversity of coordination environments depending on their oxidation state, mostly ranging from octahedral, square-pyramidal, tetrahedral and linear-based. 421–426 The possibility of tuning oxidation states not only allows control of the coordination environment, but also shifting of the donor atom preferences (Fig. 9).…”

Unlocking the catalytic potential of gold(ii) complexes: a comprehensive reassessment

“…20 In contrast, gold(III) complexes, featuring a [Xe]5d 8 electronic configuration, favour square-planar coordination. 21 On the other hand, the prevalence of gold complexes showing a formal oxidation state +II has exhibited a marked increase, making this oxidation state almost conventional in contemporary gold chemistry. However, the abundance of gold (II) complexes remains limited when compared to their more frequently encountered gold(I) and gold(III) counterparts (Fig.…”
