PY3 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PY3 cluster. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a single-bond geometry to one P(1) atom. The Y(1)-P(1) bond length is 0.85 Å. In the second Y site, Y(2) is bonded in a distorted single-bond geometry to one Y(3) atom. The Y(2)-Y(3) bond length is 0.82 Å. In the third Y site, Y(3) is bonded in a 1-coordinate geometry to one Y(2) and one P(1) atom. The Y(3)-P(1) bond length is 0.94 Å. P(1) is bonded in a distorted L-shaped geometry to one Y(1) and one Y(3) atom.
