Diffusion of Silver in Silver Sulfide.

Can mono- or di-butyltin chlorides produce tributyltin chloride at elevated temperatures? Implications for applications in chemical vapour deposition

“…With two alkyl groups on tin, any such destabilisation will be trivial. With one alkyl and one chloro ligand, the alkyl group can inductively, and perhaps hyperconjugatively, release electrons to accommodate the demand of the positive centre at tin, to produce a more stable system [33].…”

Preparation of Ag2S Nanocrystals of Predictable Shape and Size

“…[17] It has been reported that Ag ions diffuse readily among the interstitial sites and thus lead to a facile morphological transformation. [18] We find that the enhanced diffraction peaks in Figure 4 c correspond to the major lines of the cubic b-Ag 2 S pattern. Hence it seems that b-phase crystals are formed under reaction conditions we employed, although the exact mechanism is unclear at the moment.…”

Synthesis of faceted and cubic Ag2S nanocrystals in aqueous solutions

“…Ag 2 S is known to exist in three modifications: (1) the monoclinic α-phase at room temperature, (2) the body-centered cubic β-phase at temperatures between 178 and 600 • C, and (3) the face-centered cubic γ -phase above 600 • C. All these phases share a common cubic or near-cubic framework of anions, with the cations distributed at different interstitial locations [46]. It has been reported that Ag ions diffuse readily among the interstitial sites and thus lead to a facile morphological transformation [47]. Therefore, it is reasonable for Ag 2 S nanocrystals with monoclinic phase to take on a shape of cube under proper conditions and cubic α-Ag 2 S nanocrystals have also been obtained by thermolysis of organometallic complexes [37,38].…”
