WRe2Si crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WRe2Si cluster. W(1) is bonded in a 3-coordinate geometry to one Re(1), one Re(2), and one Si(1) atom. The W(1)-Re(1) bond length is 1.27 Å. The W(1)-Re(2) bond length is 0.86 Å. The W(1)-Si(1) bond length is 1.46 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a distorted single-bond geometry to one W(1) atom. In the second Re site, Re(2) is bonded in a single-bond geometry to one W(1) atom. Si(1) is bonded in a single-bond geometry to one W(1) atom.
