Mg2Sr crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 12-coordinate geometry to eight Mg atoms. There are a spread of Sr–Mg bond distances ranging from 3.56–3.59 Å. In the second Sr site, Sr is bonded in a 12-coordinate geometry to eight Mg atoms. There are a spread of Sr–Mg bond distances ranging from 3.48–3.62 Å. There are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 8-coordinate geometry to two equivalent Sr and six Mg atoms. There are two shorter (3.16 Å) and four longer (3.42 Å) Mg–Mg bond lengths. In the second Mg site, Mg is bonded in a 8-coordinate geometry to four equivalent Sr and four Mg atoms. Both Mg–Mg bond lengths are 3.29 Å. In the third Mg site, Mg is bonded in a 6-coordinate geometry to six Sr atoms. In the fourth Mg site, Mg is bonded in a 10-coordinate geometry to four Sr and six Mg atoms.
