Samarium(III) fluoride (SmF3) is a slightly hygroscopic solid fluoride. At room temperature, it has orthorhombic structure with space group Pnma - β-YF3 type with lattice constants a = 6.669, b = 7.059, c = 4.405 (.10-1 nm). Above 495 °C, it has the rhombohedral LaF3 structure (space group P3cl) - with lattice constants a = 7.07, c = 7.24 (.10-1 nm).[1]
Conditions/substances to avoid are: open flame, moisture, strong acids.
