Silber(I)‐catena‐Polysilicat Kristallzüchtung und Strukturanalyse

Abstract

Ag2SiO3 wurde unter hydrothermalen Bedingungen aus den binären Komponenten als Pulver und Einkristalle dargestellt. Nach der Röntgenstrukturanalyse (P212121; a = 452,7(1), b = 710,8(1), c = 995,9(1) pm; Z = 4; 1387 Reflexe, 57 Parameter; R = 0,06) handelt es sich um ein catena‐Polysilicat mit einer Zweiereinfachkette. Das UV/VIS‐Spektrum zeigt eine Absorptionskante bei 19 700 cm−1.

Synthesis and Characterization of the Chain Borosulfates (NH4)3[B(SO4)3] and Sr[B2(SO4)4]

“…Hence, the anion can be described by the Niggli formula 1 ∞ [B(SO 4 ) 2 (SO 4 ) 2/2 ] 3– }. By eying the corner sharing connection pattern of the supertetrahedra with a B:S ratio of 1:3, unbranched zweier single chains result, comparable to the silicate chains in Ag 2 [SiO 3 ] …”

“…By eying the corner sharing connection pattern of the supertetrahedra with a B:S ratio of 1:3, unbranched zweier single chains result, comparable to the silicate chains in Ag 2 [SiO 3 ]. [15] Figure 1. Crystal structure of (NH 4 ) 3 (10) pm].…”

Crystal structure of silver metagermanate, Ag2GeO3

“…The initial structural parameters of Ag 2 GeO 3 were taken from those of Ag 2 SiO 3 (Jansen et al , 1991). There are six independent sites (i.e., two Ag site, one Ge site, and three O sites) with the Wyckoff position 4 a in the unit cell.…”

“…Crystal structures of these silver germanates, except for Ag 2 GeO 3 , have been successfully determined. Parts of these silver germanates were confirmed to be isostructural with the corresponding silver silicates such as Ag 5 SiO 4 (Linke and Jansen, 1994), Ag 4 SiO 4 (Klein and Jansen, 2008), Ag 6 Si 2 O 7 (Jansen, 1977; Linke and Jansen, 1996a), Ag 10 Si 4 O 13 (Jansen and Keller, 1979),Ag 2 SiO 3 (Jansen et al , 1991), and Ag 2 Si 2 O 5 (Liebau, 1961). The most remarkable common feature of these structures is the relatively short silver-silver distances.…”

Fabrication of Ag2SiO3/SiO2 Composite Nanotubes Using a One‐Step Sacrificial Templating Solution Approach

“…[25] Ag 2 SiO 3 is an important ionic conductor material but has rarely been studied. [26] Recently, we have shown that a family of metal tungstate and molybdate nanowires/nanorods can be easily synthesized by a facile hydrothermal recrystallization technique. [27] Here, we report an efficient route for transforming uniform Ag 6 Mo 10 O 33 nanowires into well-defined hollow Ag 2 SiO 3 / SiO 2 composite nanotubes by a facile sacrificial template approach at room temperature.…”
