WP is alpha carbon monoxide-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two phosphane;tungsten molecules. W(1) is bonded in a single-bond geometry to one P(1) atom. The W(1)-P(1) bond length is 0.26 Å. P(1) is bonded in a single-bond geometry to one W(1) atom.
