Crystal structure of Ho2Ni0.8Si1.2 [Zr2Ni0.48P-type; oP32; Pnma (No. 62)] viewed along the b axis. The Ho, Ni1, Ni2/Si, Si1, and Si2 atoms are represented as red, turquoise, blue, light-gray, and dark-gray spheres, respectively. The distinctive structural fragment built up of five differently oriented trigonal prisms is highlighted in transparent blue.
