The crystal structure described by HoRuGa3 crystallizes in the cubic Pm-3m space group. Ho(1) is bonded in a 14-coordinate geometry to four equivalent Ru(1), two equivalent Ga(1), and eight equivalent Ga(2) atoms. Ru(1) is bonded to four equivalent Ho(1) and eight equivalent Ga(2) atoms to form distorted RuHo4Ga8 cuboctahedra that share corners with four equivalent Ru(1)Ho4Ga8 cuboctahedra, edges with four equivalent Ga(1)Ho6 octahedra, and faces with eight equivalent Ru(1)Ho4Ga8 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to six equivalent Ho(1) atoms to form GaHo6 octahedra that share corners with six equivalent Ga(1)Ho6 octahedra and edges with twelve equivalent Ru(1)Ho4Ga8 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to three equivalent Ho(1), three equivalent Ru(1), and three equivalent Ga(2) atoms. is represented by the CIF file [CIF]
