YRuGa3 crystallizes in the cubic Pm-3m space group. Y(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 Y(1) and eight equivalent Ga(2) atoms to form distorted RuY4Ga8 cuboctahedra that share corners with four equivalent Ru(1)Y4Ga8 cuboctahedra, edges with four equivalent Ga(1)Y6 octahedra, and faces with eight equivalent Ru(1)Y4Ga8 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to six equivalent Y(1) atoms to form GaY6 octahedra that share corners with six equivalent Ga(1)Y6 octahedra and edges with twelve equivalent Ru(1)Y4Ga8 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 Y(1), three equivalent Ru(1), and three equivalent Ga(2) atoms.
