A series of new RE2BiO2 compounds (RE = Nd, Tb, Dy, Ho) has been synthesized from elemental bismuth, REBi, and RE2O3 in all-solid state reactions in sealed tantalum ampoules at 1770 K. The dark grey metallic compounds adopt the anti-ThCr2Si2 type of structure (I4/mmm, tI10), according to X-ray single crystal structure analysis. As a main structural feature, there are PbO analogous slabs, [REO]+, and
由元素铋、REBi 和 RE2O3 在密封的钽安瓿中于 1770 K 进行全固态反应合成了一系列新的 RE2BiO2 化合物(RE = Nd、Tb、Dy、Ho)。 -ThCr2Si2 型结构 (I4/mmm, tI10),根据 X 射线单晶结构分析。作为主要结构特征,有 PbO 类似的板条 [REO]+ 和 44 个 Bi2- 阴离子网,沿 c 轴交替堆叠。
