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.
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. Both Sr(1)-Sr(1) bond lengths are 3.58 Å. There are a spread of Sr(1)-Mg(1) bond distances ranging from 3.45-3.71 Å. Mg(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1) atoms.
