摘要
首次用X射线单晶法(牛津衍射X’口径四圆衍射仪，MoKα辐射)研究了TmNi5化合物的Сrystal结构:cacu5型结构，Pearson符号hP6，空间群P6/mmm, a = 4.8684(12)， c = 3.9541(7) Å， R1 = 0.0529, wR2 = 0.1835。与过渡金属含量高的金属间化合物类似，标题结构中的原子具有相当高的配位数:铥为20，镍为12。
Сrystal structure of the TmNi5 compound has been investigated by means of X-ray single crystal method (Oxford Diffraction X’calibur four-circle diffractometer, MoKα radiation) for the first time: CaCu5-type structure, Pearson symbol hP6, space group P6/mmm, a = 4.8684(12), c = 3.9541(7) Å, R1 = 0.0529, wR2 = 0.1835 for 80 reflections. Similarly to intermetallic compounds with high transition metal content, atoms in the title structure have rather high coordination numbers: 20 for thulium and 12 for nickel.
