The structure described by EuRu4Sb12 crystallizes in the cubic Im-3 space group. Eu(1) is bonded to twelve equivalent Sb(1) atoms to form EuSb12 cuboctahedra that share faces with eight equivalent Ru(1)Sb6 octahedra. Ru(1) is bonded to six equivalent Sb(1) atoms to form RuSb6 octahedra that share corners with six equivalent Ru(1)Sb6 octahedra and faces with two equivalent Eu(1)Sb12 cuboctahedra. The corner-sharing octahedral tilt angles are 55°. Sb(1) is bonded in a 5-coordinate geometry to one Eu(1), two equivalent Ru(1), and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
