Silver halides have unique features in solid state physics because their properties are considered to be of borderline nature between ionic and covalent bonding. In AgCl, the self-trapped hole (STH) is centered and partly trapped in the cationic sublattice, forming an Ag(2+) ion inside of a (AgCl(6))(4-) complex as a result of the Jahn-Teller distortion. The STH in AgCl can capture an electron ...

The energy loss function (ELF) describes the interaction between electrons and matter in solids. Electron inelastic mean free paths (IMFPs), which are important basic parameters for describing electron scattering matter, have been calculated theoretically from ELFs of materials. These essential understanding quantitative surface spectroscopies, such as Auger X-ray photoelectron spectroscopy. Ho...

electronic, magnetic, optical a g g r e g a t e s o f and chemical properties are atoms/molecules C found to be very different containing a few to several from their bulk form and t h o u s a n d s o f depend sensitively on their atoms/molecules.

Reactions of N-diphenylphosphanylmethyl-4-aminopyridine (dppmapy) with K[Ag(CN)(2)], Ag(dca) (dca = dicyanamide), AgSCN, AgCl, AgBr or AgI gave rise to six [Ag(2)X(2)]-based (X = CN(-), dca, SCN(-), Cl(-), Br(-) and I(-)) compounds, [{Ag(2)(CN)(2)(dppmapy)}.0.5CHCl(3)](n) (1), [Ag(2)L(2)(dppmapy)(2)](n) (2: L = dca; 3: L = SCN), [{Ag(2)L(2)(dppmapy)(2)}.sol](n) (4: L = Cl, sol = 0.5MeOH.0.5CH(2...

Reaction of deprotonated 2,5-bis(2'-pyridyl)pyrrole (HPDPH) with AgOTf (where OTf(-) = triflato) in THF readily yields a yellow triangular Ag3 complex [(PDPH)Ag]3 (1), of which the av. AgAg distance is 2.902 Å. A mixture of HPDPH and AgOTf reacts with PPh3 to afford a linear Ag3 complex [Ag{(PDPH)Ag(PPh3)}2](OTf) (2·OTf), whereas it reacts with diethyl phosphite in the presence of Li[N(SiMe3)2]...

The polarographic or voltammetric behaviour of a selected group of tetra-alkyl ammonium halides and related compounds in liquid sulphur dioxide was investigated, using a stationary disk platinum indicating micro-electrode and a silver/silver-bromide reference electrode withcompensation for the IR drop of the solution. The electrochemical oxidation-reduction patterns are characteristic of the na...
