The material structure described by Mg2Sr crystallizes in the monoclinic C2/c space group. Sr(1) is bonded to two equivalent Sr(1) and ten equivalent Mg(1) atoms to form a mixture of distorted corner, edge, and face-sharing SrSr2Mg10 cuboctahedra. Mg(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1) atoms. is represented by the CIF card [CIF]
