Re Os Os W
WReOs2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WReOs2 clusters. W(1) is bonded in a single-bond geometry to one Re(1) atom. The W(1)-Re(1) bond length is 0.72 Å. Re(1) is bonded in a single-bond geometry to one W(1) and one Os(2) atom. The Re(1)-Os(2) bond length is 1.64 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 1-coordinate geometry to one Os(2) atom. The Os(1)-Os(2) bond length is 1.33 Å. In the second Os site, Os(2) is bonded in a 2-coordinate geometry to one Re(1) and one Os(1) atom.
