Crystal structures and ionic conductivities of ternary derivatives of the silver and copper monohalides—II: ordered phases within the (AgX)x–(MX)1−x and (CuX)x–(MX)1−x (M=K, Rb and Cs; X=Cl, Br and I) systems

Supercubooctahedron (Cs6Cl)2Cs5[Ga15Ge9Se48] Exhibiting Both Cation and Anion Exchange

“…The of RbÀCl bond lengths of 3.328(2)-3.354(6) i n4are close to that of RbCl (3.364 ). [39] In the case of 5,t he free-occupancy refinement indicated that about 20 %o fC s1 and Cs2, which form octahedra around the interstitial Cl anion, was exchanged by K( Cs1:C s/K = 0.822(3)/ 0.178(3);C s2:C s/K = 0.799(2)/0.201(2);s ee the Supporting Information, Ta ble S2e) Cs3, Cs4, and Cs5 were not attacked by Ku nder the experimental conditions. The coexistence of Cs/K was confirmed by the elemental analysis (see the Supporting Information, Figure S3e).…”

Phase Equilibria in Copper(I) Bromide-MBr Systems (M = Li, Na, K)

“…In the CuBr-KBr system one intermediate compound, K 2 CuBr 3 , melting incongruently, was found [1,2]. It was prepared by precipitation from a hot aqueous solution [2,3]. Refined crystal structure data on K 2 CuBr 3 were recently published by Hull and Berastegui [3].…”

(C5H12N)Cu2Br3: A Piperidinium Copper(I) Bromide with [Cu2Br3]− Ladders

“…The structural motif of ladders built from edge-sharing tetrahedra is known from alkali copper and silver halides, e.g., CsCu 2 Cl 3 , CsCu 2 Br 3 [1], CsCu 2 I 3 [2], CsAg 2 I 3 [3], also from chalcogenides, e.g., the mineral rasvumite,…”
