WB2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two tungsten diboride molecules. W(1) is bonded in a water-like geometry to one B(1) and one B(2) atom. The W(1)-B(1) bond length is 0.50 Å. The W(1)-B(2) bond length is 0.50 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one W(1) atom. In the second B site, B(2) is bonded in a single-bond geometry to one W(1) atom.
