SrWMn2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 3-coordinate geometry to three equivalent W(1) and one Mn(1) atom. There is one shorter (3.18 Å) and two longer (3.37 Å) Sr(1)-W(1) bond lengths. The Sr(1)-Mn(1) bond length is 3.83 Å. W(1) is bonded in a single-bond geometry to three equivalent Sr(1), one Mn(2), and four equivalent Mn(1) atoms. The W(1)-Mn(2) bond length is 1.44 Å. There are a spread of W(1)-Mn(1) bond distances ranging from 2.23-2.73 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 9-coordinate geometry to one Sr(1), four equivalent W(1), and four equivalent Mn(2) atoms. There are a spread of Mn(1)-Mn(2) bond distances ranging from 1.96-2.52 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one W(1) and four equivalent Mn(1) atoms.
