YAsP2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YAsP2 cluster. Y(1) is bonded in a distorted single-bond geometry to one As(1), one P(1), and one P(2) atom. The Y(1)-As(1) bond length is 0.83 Å. The Y(1)-P(1) bond length is 1.72 Å. The Y(1)-P(2) bond length is 1.72 Å. As(1) is bonded in a single-bond geometry to one Y(1) and one P(1) atom. The As(1)-P(1) bond length is 1.73 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a distorted single-bond geometry to one Y(1) and one As(1) atom. In the second P site, P(2) is bonded in a single-bond geometry to one Y(1) atom.
