The structure described by Mg2Sr is Molybdenite structured and crystallizes in the hexagonal P6_3/mmc space group. Sr(1) is bonded to six equivalent Sr(1) and six equivalent Mg(1) atoms to form a mixture of distorted face, corner, and edge-sharing SrSr6Mg6 cuboctahedra. Mg(1) is bonded in a 6-coordinate geometry to three equivalent Sr(1) and three equivalent Mg(1) atoms. is represented by the CIF card [CIF]
