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 = 6669 pm b = 7059 pm c = 4405 pm. Above 495 °C it has the rhombohedral LaF3 structure (space group P3cl) – with lattice constants a = 707 c = 724 pm.Conditions/substances to avoid are: open flame moisture strong acids.
