Abstract The indide YIrIn was synthesized from the elements in a sealed tantalum ampoule in a high-frequency furnace. YIrIn adopts the ZrNiAl type. The crystal structure was refined from single-crystal X-ray diffractometer data: P6–2m, a = 750.63(6), c = 392.04(3) pm, wR = 0.0346, 308 F 2 values and 16 variables. Refinement of the occupancy parameters revealed a small degree of Ir/In mixing (0.912(9) Ir2/0.088(9) In1) on the 2d site. The YIrIn structure contains two crystallographically independent iridium sites, both with tri-capped trigonal prismatic coordination: Ir1@In6Y3 and Ir2@In3Y6.

具有 ZrNiAl 型结构的 YIrIn

摘要 将元素置于密封的钽安瓿中，在高频炉中合成了吲哚YIrIn。YIrIn采用ZrNiAl型。晶体结构是从单晶 X 射线衍射仪数据中提炼出来的：P6–2m，a = 750.63(6)，c = 392.04(3) pm，wR = 0.0346，308 F 2 值和 16 个变量。占用参数的细化揭示了 2d 站点上的小程度 Ir/In 混合（0.912(9) Ir2/0.088(9) In1）。YIrIn 结构包含两个晶体学上独立的铱位点，均具有三顶三角棱柱配位：Ir1@In6Y3 和 Ir2@In3Y6。
