WRe2Os is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WRe2Os clusters. W(1) is bonded in a 3-coordinate geometry to two equivalent Re(1) and one Os(1) atom. Both W(1)-Re(1) bond lengths are 0.19 Å. The W(1)-Os(1) bond length is 0.19 Å. Re(1) is bonded in a 3-coordinate geometry to one W(1), one Re(1), and one Os(1) atom. The Re(1)-Re(1) bond length is 0.19 Å. The Re(1)-Os(1) bond length is 0.19 Å. Os(1) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Re(1) atoms.
