TaW2P crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaW2P cluster. Ta(1) is bonded in a 2-coordinate geometry to one W(1) and one W(2) atom. The Ta(1)-W(1) bond length is 1.56 Å. The Ta(1)-W(2) bond length is 1.77 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one Ta(1) atom. In the second W site, W(2) is bonded in a distorted bent 150 degrees geometry to one Ta(1) and one P(1) atom. The W(2)-P(1) bond length is 1.08 Å. P(1) is bonded in a distorted single-bond geometry to one W(2) atom.
