Kristallstruktur und elektrische Leitfähigkeit von Ag3YCl6

Abstract: Polykristallines YCl3 reagiert mit einem Einkristall von AgCl in Sandwich‐Anordnung (365°C, 140 h) an der Kontaktfläche zu einer Produktschicht aus vorwiegend einkristallinem Ag3YCl6. Die daraus isolierten Einkristalle der Tieftemperaturform (Ag3YCl6–I) wandeln sich bei 350°C in eine Hochtemperaturform (Ag3YCl6–II) um. Die Kristallstruktur von Ag3YCl6 I (a = 686,69 pm, c = 1 830,5 pm, trigonal, R3, Z = 3) entspricht der des Na3GdCl6–I. Es liegt eine strukturelle Fehlordnung vor, wobei zwei Ag+‐Ionen vier Oktae… Show more

“…Thus the migration paths of the Ag + ions are blocked and no long range ion mobility is possible since the structure of the anionic lattice does not offer non‐intermittent migration paths for ionic conduction and only a local mobility is observed. The Ag–Cl distances amount 2.582(6) [Ag(4)–Cl(2) VII ], 2.653(6) [Ag(4)–Cl(3)], and 2.976(6) Å [Ag(4)–Cl(3) VI ] for the different silver sites and are comparable for example with the Ag–Cl distances in Ag 3 YCl 6 (2.570 to 2.733 Å) 15. Ag 3 YCl 6 also contains disordered silver ions with an elongated electron density inside a pair of face sharing octahedra.…”

“…The lattice parameters of the synthesized hexagonal Ag 3 YCl 6 were determined to be a = 6.8822(10) Å and c = 18.338(3) Å, which are consistent with the previously reported values (a = 6.8669( 14) Å and c = 18.3050(50) Å). 14 Upon the application of hydrostatic pressure, a clear phase transition was observed around 1.5 GPa in the in situ XRD pattern (Fig. 1a and S1 †).…”

“…While it is known that heating the hexagonal Ag 3 YCl 6 leads to phase transformation at 350 °C, the resulting phase remains unsolved. 14 In this study, we showed, for the first time, that highpressure phase transformation converts hexagonal Ag 3 YCl 6 to the novel, monoclinic Ag 3 YCl 6 with the aid of synchrotron XRD and atomistic calculations.…”
