SrReMn2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), four equivalent Re(1), and one Mn(2) atom. All Sr(1)-Sr(1) bond lengths are 2.83 Å. There are a spread of Sr(1)-Re(1) bond distances ranging from 3.15-3.55 Å. The Sr(1)-Mn(2) bond length is 3.93 Å. Re(1) is bonded in a single-bond geometry to four equivalent Sr(1) and one Mn(1) atom. The Re(1)-Mn(1) bond length is 0.57 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Re(1) and four equivalent Mn(2) atoms. There are a spread of Mn(1)-Mn(2) bond distances ranging from 1.94-2.55 Å. In the second Mn site, Mn(2) is bonded in a 5-coordinate geometry to one Sr(1) and four equivalent Mn(1) atoms.
