Holmium diantimonide is an inorganic compound with the chemical formula HoSb₂. It is one of the antimonides of holmium.^[2] It can be obtained by reacting holmium and antimony at a certain temperature (1000~1500 °C) and pressure (30~65 kbar).^[3] X-ray diffraction shows its space group C222, unit cell parameters a=3.343 Å, b=5.790 Å, c=7.840 Å, Z=2.^[4]

HoSb₂ is also the crystal structure prototype of some compounds. Compounds belonging to the HoSb₂ structure include LuSb₂, YSb₂, etc.^[5]
