“…The 1 H and 31 P NMR spectra of 14b were obtained only at room temperature but showed similar features to those of 14a. Despite THT being a weakly coordinating ligand, it can yield stable Au(I) species, although only a few of them have been characterized by X-ray crystallography [27,28]. The Au-S and Au-P distances in 14a As part of a bioorganometallic project involving the linking of an organoruthenium moiety to a commercial anticancer drug, the complex [(p-O 2 N-C 6 H 4 -CO-NH-CH 2 -C 6 H 5 )RuCl 2 ] 2 (15), was treated with a number of ligands, such as DMSO, phosphines, etc., that cleave the halogen bridges and yield the desired (arene)RuCl 2 L systems.…”

This chapter focuses mainly on closed shell gold(I) atoms which are found to feel attraction among themselves. This attraction is able to modify expected geometries or support one-, two-or three-dimensional arrays and also leads to interesting properties. Closed shell metal cations are expected to repel each other. Nevertheless, an important number of examples containing [d 8 -d 10 -s 2 ] interactions are known. Particularly strong evidence has been accumulated on the attraction between two or more d 10 shells. In the case of gold(I) such attraction between two or more monovalent gold(I) ions in compounds has been observed structurally for a long time. In these situations the gold centers approach each other to a distance of between 2.7 and 3.3 Å. This range includes the distance between gold atoms in gold metal and approaches, or even overlaps with the range of distances found in the few real Au-Au single bonds. Schmidbaur coined the name aurophilic attraction in 1990 and defined it as the unprecedented affinity between gold atoms even with closed-shell electronic configurations and equivalent electrical charges [1]. Since that moment, aurophilicity has become one of the hot topics in gold chemistry, at first with the aim of understanding such interaction, more recently because of the observation that it may play an important role in interesting properties, thus understanding and modulating aurophilic interactions could help to govern these properties, which include the optical behavior. Although different origins are possible for the luminescent emissions of coordination complexes, such as intraligand transitions (ILT), ligand to metal or metal to ligand charge transfer transitions (LMCT, MLCT) and metal centered (MCT) transitions, in many luminescent gold complexes the emissions have been related to the presence of aurophilic interactions.Information about aurophilicity and chemical situations in which it is observed may be found in different works that may be classified as those which analyse closed shell interactions in general [2], those focused on aurophilicity [1,3], and others which analyze the role of these interactions in coordination [4] and organometallic gold Modern Supramolecular Gold Chemistry: Gold-Metal Interactions and Applications.
