Sr2WOs crystallizes in the triclinic P1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted single-bond geometry to two equivalent Sr(2) and one W(1) atom. There is one shorter (1.81 Å) and one longer (2.26 Å) Sr(1)-Sr(2) bond length. The Sr(1)-W(1) bond length is 2.26 Å. In the second Sr site, Sr(2) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Os(1) atoms. There is one shorter (3.00 Å) and one longer (3.92 Å) Sr(2)-Os(1) bond length. W(1) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one Os(1) atom. The W(1)-Os(1) bond length is 1.25 Å. Os(1) is bonded in a distorted single-bond geometry to two equivalent Sr(2) and one W(1) atom.
