including multidrug resistant strains. It is, however, inactive toward Gram-negative bacteria, for which we are in dire need of new therapies. In this work, 40 auranofin analogues were synthesized by varying the structures of the thiol and phosphine ligands, and their activities were tested against ESKAPEpathogens. The study identified compounds that exhibited bacterial inhibition (MIC) and killing

A series of mixed ligandgold(I) complexes with thiourea (Tu) and various phosphines, [R3PAuTu]Cl, have been prepared and characterized by elemental analysis, IR and NMR (13C, 15N and 31P) spectroscopies and X-ray crystallography. The spectral data of all complexes are consistent with the sulfur coordination of thiourea to gold(I). The single crystalX-raystructure of the complex [Cy3P–Au–Tu]Cl revealed

the solid state and in solution, the neutral dinuclear gold(I) complexes [12‐(R3PAu)2CC‐closo‐1‐CB11H11] (R=Me, Et) dimerize to tetranuclear gold(I) clusters held together by aurophilic interactions. For the Et3P complex, the dimer and the monomer exist in equilibrium in solution at 25 °C. In contrast, even at 75 °C only dimers (AuI4 clusters), are observed for the Me3P complex (see structure: C black
31P n.m.r. studies on trialkylphosphinegold(I) derivatives of ruthenium carbide clusters: synthesis and X-ray crystal structures of [Ru6C(CO)16(AuPMePh2)2] and [Ru5WC(CO)17(AuPEt3)2]

Reaction of the anions [Ru6C(CO)16]2– and [Ru5WC(CO)17]2– with ClAuPR3(R = alkyl, aryl) yields [Ru6C(CO)16(AuPR3)2] and [Ru5WC(CO)17(AuPR3)2], respectively; X-ray crystallography has shown that two gold atoms adopt a different geometry in each case and subsequent low-temperature 31P1H} n.m.r. studies have shown that these compounds exist as isomeric species in solution.

Reactions of alkylgold(I) complexes [AuRL](R = Me, L = PMe3, PMe2Ph, or PMePh2; R = Et, L = PMePh2) with hexafluorobut-2-yne give first the mixed-oxidation-state complexes [LAu(F3C)CC(CF3)}AuR2L], which react further to give either the binuclear gold(I) complexes [LAu(F3C)CC(CF3)}AuL] or the products of cis in-sertion of the alkyne into the original Au–C bond, [AuL(F3C) CCR (CF3)}].
