“…The 1 H NMR spectrum yielded a single product; however, the mixture becomes insoluble over time, which we attribute to the formation of a polymeric structure. Further, the Au analog has been isolated as a polymer with repeating dinuclear units, {Au 2 [CS 2 (2,6-Me 2 C 6 H 3 NC(H)NC 6 H 3 Me 2 )] 2 } n , that are bridged by aurophilic interactions …”

Dinuclear Cu(I) and Ag(I) complexes, Cu2[(2,6-Me2C6H3N)2C(H)]2, 1, Ag2[(2,6-Me2C6H3N)2C(H)]2, 2, Cu2[2,6-(i)Pr2C6H3N)2C(H)]2, 3, and Ag2[(2,6-(i)Pr2C6H3N)2C(H)]2, 4, were synthesized from reactions of [Cu(NCCH3)4][PF6] with Na[(2,6-R2C6H3N)2C(H)] and AgO2CCH3 with [Et3NH][(2,6-R2C6H3N2C(H)], R = Me, (i)Pr. Carbon disulfide was observed to insert into the metal-nitrogen bonds of 1 to produce Cu4[CS2(2,6-Me2C6H3NC(H)═NC6H3Me2)]4, 5, with a Cu4S8 core, which represents a rare transformation of dinuclear to tetranuclear species. Insertion is also observed with 2 and CS2, with the product likely being polymeric, 6. With the (i)Pr-derivatives, CS2 insertion was also observed, albeit at much slower rate, with 3 and 4 producing hexanuclear clusters, M6[CS2(2,6-Me2C6H3NC(H)═NC6H3Me2)]6, M = Cu, 7; Ag, 8. Complexes 1 and 5 display green luminescence, a feature not shared by their Ag(I) analogs nor with 3. Notably, oxygen acts as a collisional quencher of the luminescence from 1 and 5 at a rate faster than most metal-based quenchometric O2 sensors. For example, we find that complex 1 can be rapidly and reversibly quenched by oxygen, presenting a nearly 6-fold drop in intensity upon switching from nitrogen to an aerated atmosphere. The results here provide a platform from which further group 11 amidinate reactivity can be explored.

“…[181][182][183][184] In this context, many gold string compounds are supported by bidentate dithiophosphate, 185-189 dithiocarboxylate, 190,191 diselenophosph(in)ate 192,193 or related ligand systems. [194][195][196][197][198][199] The Ch-X-Ch donor sites (Ch = chalcogenide, X = C, P) exhibit a low steric demand, which allows for the formation of gold strings comprising intermolecular connected homoleptic digold complexes (Fig. 23).…”

“…The complexes are stable at room temperature. To probe the reactivity of gold-nitrogen bonds, Justin Walensky and his research group examined the insertion chemistry of gold(I) amidinate complexes with carbon disulfide as well as oxidation with cesium tribromide [15]. They also examined the reactivity of CS2 and CsBr3 with the previously reported dinuclear gold(I) amidinate complex.…”

Basic chemistry of gold tells us that it can bond to sulfur, phosphorous, nitrogen, and oxygen donor ligands. The Frontiers in Gold Chemistry Special Issue covers gold complexes bonded to the different donors and their fascinating applications. This issue covers both basic chemistry studies of gold complexes and their contemporary applications in medicine, materials chemistry, and optical sensors. There is a strong belief that aurophilicity plays a major role in the unending applications of gold.
