CsW2Os crystallizes in the trigonal R3m space group. Cs(1) is bonded in a single-bond geometry to one W(2), three equivalent W(1), and four equivalent Os(1) atoms. The Cs(1)-W(2) bond length is 0.40 Å. All Cs(1)-W(1) bond lengths are 2.71 Å. There are three shorter (2.72 Å) and one longer (3.56 Å) Cs(1)-Os(1) bond length. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted hexagonal planar geometry to three equivalent Cs(1) and three equivalent Os(1) atoms. All W(1)-Os(1) bond lengths are 2.71 Å. In the second W site, W(2) is bonded in a single-bond geometry to one Cs(1) and three equivalent Os(1) atoms. All W(2)-Os(1) bond lengths are 2.71 Å. Os(1) is bonded in a 10-coordinate geometry to four equivalent Cs(1), three equivalent W(1), and three equivalent W(2) atoms.
