Synthesis and Crystal Structure of KSmLaF6
Abstract:
KSmLaF6 was synthesized by reducing Sm0.5La0.5F3 with potassium vapor at 300℃ or 420℃. The new compound has two phases:the low-temperature phase is trigonal crystal system with lattice parameters a=0.6493(2) nm, c=0.3777(1) nm, c/a=0.582, Z=1, sapce group P3; and the high-temperature phase is cubic crystal system with lattice parameters a=0.5873(3) nm, Z=4/3, space group Fm3m.
