|Section2= |Section3= |Section7= |Section4= }} 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'' = 666,9 pm, ''b'' = 705,9 pm, ''c'' = 440,5 pm. Above 495 °C, it has the rhombohedral LaF3 structure (space group ''P3cl'') – with lattice constants ''a'' = 707, ''c'' = 724 pm.〔K Rotereau et al.: ''The high-temperature phase transition in samarium fluoride, SmF3: structural and vibrational investigation'', J. Phys.: Condens. Matter, 1998, 10, 1431–1446, .〕 Conditions/substances to avoid are: open flame, moisture, strong acids. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Samarium(III) fluoride」の詳細全文を読む スポンサード リンク
