Remarkable Luminescence Behaviors and Structural Variations of Two-Coordinate Gold(I) Complexes

“…This strategy has been applied to produce some nearly linear, trinuclear Au(I) complexes. The colorless ions, [Au 3 (dpmp) 2 ] 3+ and [Au 3 (dmmp) 2 ] 3+ , shown in Scheme 6 are prominent examples [64][65][66][67] 1 triplet, while the high energy band has been assigned to an intraligand transition of the phosphine [64]. A number of calculations have been performed that provide a theoretical background for understanding the absorption and emission processes and the effects of metal ion separation [68,69].…”

“…Only a short section at the end discusses a few relevant examples from the extensive literature on ligand-bridged, bi-and poly-nuclear complexes. Several articles are available that examine the fundamental coordination chemistry of gold [1,2]. Gold(I) complexes generally exhibit coordination numbers of two, three, or four, but two-coordinate complexes are particularly prevalent and are the focus of this article.…”

Polymorphism and luminescent behavior of linear, two-coordinate gold(i) complexes

“…Au contacts are shorter than 3.6 Å (11,12). Considerable attention has been paid to the nature of the attraction of gold(I) centers to one another for the synthesis of new molecules (13,14) and to create a better understanding of the physical forces involved (15). Alternate theories have suggested that the aurophilic attraction is caused by either electron correlation effects strengthened by relativistic effects (16,17) or by hybridization of the 6s and 6p orbitals with the 5d orbitals (18,19).…”

Gold–Heterometal Interactions and Bonds

“…In contrast with other topics in coordination gold chemistry which grew rapidly in the last decades, for example, gold complexes with nitrogen, phosphorus or chalcogen donor ligands [11][12][13][14][15][16][17], organogold compounds [14,[18][19][20][21][22] or homo-and heteronuclear gold clusters [23][24][25][26][27], the chemistry of main group metal-gold compounds is very limited and is still waiting to be developed in the future. This section will review the literature on the structure of stoichiometrically defined molecular compounds containing Au-main group metal and AuÀHg bonds or interactions.…”
