The material structure described by Mg2Sr is Cuprite structured and crystallizes in the tetragonal P4_2/mnm space group. Sr(1) is bonded to six equivalent Mg(1) atoms to form a mixture of distorted edge and corner-sharing SrMg6 octahedra. The corner-sharing octahedral tilt angles are 65°. Mg(1) is bonded in a 4-coordinate geometry to three equivalent Sr(1) and one Mg(1) atom. is represented by the CIF file [CIF]
