摘要：

LnAl3Br12 (Ln = La, Ce, Pr, Nd, Sm, Gd) was prepared in crystalline form for the first time. The crystal structures of LaAl3Br12, PrAl3Br12, and NdAl3Br12 were determined on single crystals by X-ray methods. The isotypic compounds crystallize with trigonal symmetry, space group P 3(1)12, Z = 3. A structural comparison to lanthanoide chloroaluminates of equal composition is given and thermal decomposition of LnAl3Br12 (Ln = Nd) to the corresponding lanthanoide tribromide is described.
