Mg2Sr crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded to two equivalent Sr(1) and ten equivalent Mg(1) atoms to form a mixture of distorted face and edge-sharing SrSr2Mg10 cuboctahedra. Mg(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1) atoms.
Mg2Sr crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded to two equivalent Sr(1) and ten equivalent Mg(1) atoms to form a mixture of distorted face and edge-sharing SrSr2Mg10 cuboctahedra. Both Sr(1)-Sr(1) bond lengths are 3.67 Å. There are a spread of Sr(1)-Mg(1) bond distances ranging from 3.44-3.75 Å. Mg(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1) atoms.
