M3NS3 (M = La – Nd, Sm, Gd – Dy): Structure and Magnetism of 3:1:3-Type Nitride Sulfides of Trivalent Lanthanides Nitride sulfides of the trivalent lanthanides with the composition M3NS3 (M = La – Nd, Sm, Gd – Dy) can be prepared by the oxidation of the respective lanthanide metal with sulfur, sodium azide (NaN3), and the corresponding lanthanide tribromide (MBr3) when an additional flux (NaBr) is
M3NS3 (M = La - Nd, Sm, Gd - Dy): 3 的结构和磁性: 1: 三价镧系元素的三型氮化物硫化物 M3NS3 (M = La - Nd, Sm, Gd - Dy) 可以通过用硫、叠氮化钠 (NaN3) 和相应的三溴化镧系元素 (MBr3) 氧化相应的镧系元素金属来制备,当使用额外的助熔剂 (NaBr) 时。真空二氧化硅管中反应混合物的热处理温度范围为 800 至 900°C,确保形成明亮至深棕色、透明、板条状的单晶。正交晶体结构 (Pnma, Z = 4) 由单晶 X 射线衍射数据确定 (La3NS3: a = 1215.13 (5), b = 415.90 (2), c = 1322.12 (5) pm, Ce3NS3: a = 1206.28 (4), b = 410.16 (1), c = 1307.18 (5) pm, Pr3NS3: a = 1205.45
