Coordination modes of diphenylphosphinothioformamide in its neutral and deprotonated forms at gold(i)

Bis(1,2,3‐thiadiazole)s as Precursors in the Synthesis of Bis(alkynethiolate)gold(I) Derivatives

“…[68] The coordination around the metallic centre is nearly linear [S1-Au1-C3, 176.36 (14) complexes. [69][70][71] Additionally, the unit cell ( Figure 2) shows that packing of individual anions is influenced by very long pentafluorophenyl rings interactions (closest centroid···centroid distances of 4.122 Å, interplanar angle of 0°, perpendicular distances of 3.304 Å with slippage of 2.464 Å). Although we cannot consider strictly the presence of π-π interactions, these distances are the closest ones, to best of our knowledge, reported in pentafluorophenyl gold chemistry.…”

17 The noble metals

“…The first of these reacts with Tl(acac) to give [Au 2 L 2 ] (also P,S-and aurophilic bonding), which further reacts with Au(I) compounds giving [Au 2 L 2 (AuX) 2 ] (X ~Cl or C 6 F 5 ) with the [AuX] moiety bonded to L through the N atom. 207 The unresolved nature of gold complexes of 3,5-di-tert-butylbenzodithiolate (L), for which an improbable oxidation state of Au(IV) had been proposed, has been clarified by 197 Au Mo ¨ssbauer, IR and ESR spectroscopy in studies of [AuL 2 ] 2 and its one-electron oxidized derivative [AuL 2 ] that showed both have Au(III), the latter with an oxidized ligand. Similar conclusions were found for complexes lacking the t Bu groups.…”

Synthesis and Reactivity of (NHC)AuI–Mercaptopyridine Complexes

“…The coordination chemistry of gold complexes having sulfur and nitrogen atoms simultaneously in the same heterocycle has attracted considerable attention, and several gold complexes containing mercaptopyridines, mercaptothiazolines, mercaptourines, mercaptotetrazolates, and other related ligands have been synthesized . Although the coordination in these types of complexes is achieved through the sulfur atom, the nitrogen atom may be able to coordinate a second metal center, providing access to bimetallic complexes with several topologies and coordination environments. , …”
