SrMg crystallizes in the monoclinic C2 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 12-coordinate geometry to four equivalent Sr(2), two equivalent Mg(2), and six equivalent Mg(1) atoms. In the second Sr site, Sr(2) is bonded in a 12-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), three equivalent Mg(2), and four equivalent Mg(1) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 7-coordinate geometry to three equivalent Sr(1) and four equivalent Sr(2) atoms. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to two equivalent Sr(1) and six equivalent Sr(2) atoms.

In the first Sr site, Sr(1) is bonded in a 12-coordinate geometry to four equivalent Sr(2), two equivalent Mg(2), and six equivalent Mg(1) atoms. There are two shorter (3.87 Å) and two longer (3.98 Å) Sr(1)-Sr(2) bond lengths. Both Sr(1)-Mg(2) bond lengths are 3.58 Å. There are a spread of Sr(1)-Mg(1) bond distances ranging from 3.58-3.93 Å. In the second Sr site, Sr(2) is bonded in a 12-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), three equivalent Mg(2), and four equivalent Mg(1) atoms. There is one shorter (3.69 Å) and two longer (3.77 Å) Sr(2)-Sr(2) bond lengths. There are a spread of Sr(2)-Mg(2) bond distances ranging from 3.66-3.80 Å. There are a spread of Sr(2)-Mg(1) bond distances ranging from 3.61-3.89 Å. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 7-coordinate geometry to three equivalent Sr(1) and four equivalent Sr(2) atoms. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to two equivalent Sr(1) and six equivalent Sr(2) atoms.
