The quasi-ternary system Ag2SCdSGeS2 and the crystal structure of Ag2CdGeS4

Phase relations in the Ag2S–CdS–SnS2 system and the crystal structure of the compounds

“…The obtained diagram is similar to that of the Secontaining system, which is also eutectic with the formation of solid solution range of the ternary compound [14]. The Ag 8 GeS 6 -CdS section [12], instead, though possessing of significant solid solubility for Ag 8 GeS 6 , is of the peritectic type. …”

“…The interatomic distance Ag-S (0.2489(3) nm or 0.248(4) nm) in structure II correlates well with those in the Ag 2 CdGeS 4 (0.2522-0.2570 nm) [12] or Ag 2 HgGeS 4 (0.237-0.263 nm) [18] structure. The average interatomic distance M-S in the tetragonal version of the structure (0.262 nm) practically coincides with that of the cubic version.…”

“…1. The synthesis routine is analogous to the one we used when studying the Ag 2 S-CdS-GeS 2 system, and is described in [12]. The obtained alloys were investigated by X-ray phase analysis using a DRON 4-13 diffractometer with Cu K␣ radiation.…”

X-ray powder diffraction study of semiconducting alloys Ag1−xCuxCd2GaS4 and AgCd2Ga1−xInxS4

“…structure and their increase in the AgCd 2 Ga 0.9 In 0.1 S 4 structure compared to AgCd 2 GaS 4 is observed. The interatomic distances Ag-S, Cd-S and Ga-S are in good agreement with such distance in other compounds with diamond-like structure, such as AgGaS 2 (Ag-S, 0.256 nm; Ga-S, 0.228 nm)[17], LiGaS 2 (Ga-S, 0.2254-0.2338 nm)[18], Ag 2 CdGeS 4 (Ag-S, 0.2522-2570 nm; Cd-S, 0.2492-0.2566 nm)[19] …”

Interaction of argyrodite family compounds with the chalcogenides of II-b elements

“…We have investigated a series of isothermal sections of quasiternary systems Ag 2 X-A II X-B IV X 2 [21][22][23][24][25][26][27][28] and established that, in the majority of them, one of the stable equlibria is the equlibrium between ternary compounds of type Ag 8 B IV X 6 and the chalcogenides of the II-b group elements. All investigated zinc-and cadmium-containing systems belong to here [21,26,27,29], as well as the Ag 2 S-HgS-SnS 2 system [28].…”
