Real and Hypothetical Intermediate-Valence Ag(II)/Ag(III) and Ag(II)/Ag(I) Fluoride Systems as Potential Superconductors.
With the aim of gauging their potential as conducting or superconducting materials, we examine the crystal structures and magnetic properties of the roughly one hundred binary, ternary, and quaternary Ag(II) and Ag(III) fluorides in the solid state reported up to date. The Ag(II) cation appears in these species usually in a distorted octahedral environment, either in an [AgF](+) infinite chain ...
متن کاملComplexes of Gold(I) with a Chiral Diphosphine Ligand: A Polymer with Both Au···Ag and Ag···Ag Metallophilic Bonds
Dedicated to Professor Hubert Schmidbaur, the grand master of gold chemistry, on the occasion of his 75th birthday The chemistry of gold(I) with the ligand binap = 2,2′-bis(diphenylphosphino)-1,1′ -binaphthyl is reported. Reaction of [Au2Cl2(μ-binap)] with silver trifluoroacetate gave the corresponding complex [Au2(O2CCF3)2(μ-binap)], and crystallization in the presence of excess silver trifluo...
متن کاملSynthesis, characterization and property of a mixed-valent Ag(I)/Ag(II) coordination polymer.
A novel mixed-valent Ag(I)/Ag(II) coordination polymer {[Ag(I)(2)Ag(II)(0.5)(SO(4))(HSO(4))(pyz)(2.5)]·H(2)O}(n) (1, pyz = pyrazine) was synthesized and characterized. The results show it presents semiconducting and photoluminescent properties.
متن کاملAn upstream AG determines whether a downstream AG is selected during catalytic step II of splicing.
Specific mechanisms must exist to ensure fidelity in selecting the AG dinucleotide that functions as the 3' splice site during the second transesterification step of splicing. Here we show that the optimal location for this AG is within a narrow distance (19 to 23 nucleotides [nt]) downstream from the branch point sequence (BPS). Contrary to previous expectations, AGs located less than 23 nt fr...
متن کاملGeneration of Ag-Ag(2)O complex nanostructures by excimer laser ablation of Ag in water.
Pulsed laser ablation in liquid (PLAL) has been well established as a facile method to produce nanoparticles from bulk materials, but it is still insufficient for fabricating anisotropic and complex nanostructures, especially without the use of surfactants. Here, we demonstrate that silver (Ag) nanosheets can be produced by pulsed excimer laser ablation of bulk Ag in water via laser re-processi...
