The chlorides Ag3MCl6(M = DyLu, Y, Sc): Synthesis, structure, thermal expansion

Abstract Chlorides Ag3MCl6 have been obtained with M = DyLu, Y, Sc from AgCl/MCl3 mixtures (sealed Pyrex ampoule, 380°C, 8 d). They crystallize like Na3GdCl6‐I with a “stuffed” LiSbF6‐type structure (R3, Z = 3). Thermal expansion was followed for Ag3HoCl6 and Ag3YCl6 and is remarkably different from that of Na3GdCl6‐I.
