“…The Ag–N bond length [211.4(3) pm] is found in the same region as for [Ag(DMAP) 2 ][PF 6 ] [211.9(3) pm]20,21 at the shorter end of values reported for silver adducts with heterocyclic N‐donors. [20 and literature cited therein] The coordination around silver is quasi‐linear [178.5(1)°] as to be expected for d 10 derivatives.…”

Stacking of Benzene with Metal Chelates: Calculated CCSD(T)/CBS Interaction Energies and Potential‐Energy Curves

Accurate values for the energies of stacking interactions of nickel- and copper-based six-membered chelate rings with benzene are calculated at the CCSD(T)/CBS level. The results show that calculations made at the ωB97xD/def2-TZVP level are in excellent agreement with CCSD(T)/CBS values. The energies of [Cu(C3H3O2)(HCO2)] and [Ni(C3H3O2)(HCO2)] chelates stacking with benzene are -6.39 and -4.77 kcal mol(-1), respectively. Understanding these interactions might be important for materials with properties that are dependent on stacking interactions.

“…[14][15][16] However, it is the low toxicity of silver salts for humans that has generated interest to further explore their biomedical applications, specifically anti-microbial and anti-cancer applications. [14,[17][18][19][20] The coupling of these biologically compatible moieties generates a pharmaceutically enhanced class of compounds known as Ag (I)-NHC complexes. Anti-microbial properties of Ag(I)-NHC complexes have been the subject of investigation.…”

A series of new benzimidazolium salts as N-heterocyclic carbene (NHC) precursors has been synthesized. Reactions of these salts with Ag 2 O with varying metal-to-salt ratio facilitate the formation of a series of new binuclear and mononuclear Ag(I)-NHC complexes. All compounds were characterized using physicochemical and spectroscopic techniques. Single-crystal X-ray diffraction study reveals a binuclear structure for one of the complexes and a mononuclear one for two others. These complexes exist as cationic Ag(I)-NHC complexes with the chelation of carbene carbons to the silver centre in an almost linear manner. The compounds were screened for their anti-bacterial activities against Staphylococcus aureus (ATCC 12600) as a Gram-positive bacterium and Escherichia coli (ATCC 25922) as a Gram-negative bacterium. The results show that both bacteria appear markedly inhibited. Furthermore, the results suggest the possibility of steric variation as a modulation of the anti-bacterial activities. The nuclease activities of the compounds were assessed using gel electrophoresis and the results indicate that these complexes can cleave or degrade DNA and RNA via a non-oxidative mechanism.

“…[17] Earlier studies [18] revealed that in solution especially perfluoroalkylsilver derivatives undergo complex exchange equilibria involving a "neutral" species, AgR f , an "ionic" species, Ag[Ag(R f ) 2 ], and a "polymeric" form, [ 4-Dimethylaminopyridine (DMAP), additionally to its excellent catalytic activity in organic transformations, [19] exhibits positive features making among many other metal compounds silver derivatives easily crystallizable. [20,21] All attempts to obtain structural data for perfluoroalkylsilver(I) compounds have been limited to few examples. [2,22,23] Also the number of publications dealing with structurally characterized perfluoroarylsilver(I) derivatives is low.…”

Abstract. Attempted syntheses of AgR f ·DMAP were performed using the established route starting from AgF and Me 3 SiR f (R f = CF 3 , C 2 F 5 , C 6 F 5 ) followed by the addition of DMAP. Unexpectedly, reactions with perfluoroalkylsilver(I) derivatives yielded products, which underwent known equilibria, while exclusively the pentafluorophenyl derivative exhibits its zwitterionic nature in solution and in the solid state. Moreover, both perfluoroalkyl derivatives investigated decomposed slowly
