The structure described by Eu(MgSb)2 crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded to four equivalent Sb(1) atoms to form MgSb4 tetrahedra that share corners with six equivalent Eu(1)Sb6 octahedra, corners with six equivalent Mg(1)Sb4 tetrahedra, edges with three equivalent Eu(1)Sb6 octahedra, and edges with three equivalent Mg(1)Sb4 tetrahedra. The corner-sharing octahedral tilt angles range from 17-54°. Eu(1) is bonded to six equivalent Sb(1) atoms to form EuSb6 octahedra that share corners with twelve equivalent Mg(1)Sb4 tetrahedra, edges with six equivalent Eu(1)Sb6 octahedra, and edges with six equivalent Mg(1)Sb4 tetrahedra. Sb(1) is bonded to four equivalent Mg(1) and three equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SbEu3Mg4 pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
