CaYP2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaYP2 clusters. Ca(1) is bonded in an L-shaped geometry to one P(1) and one P(2) atom. The Ca(1)-P(1) bond length is 0.17 Å. The Ca(1)-P(2) bond length is 0.72 Å. Y(1) is bonded in an L-shaped geometry to one P(1) and one P(2) atom. The Y(1)-P(1) bond length is 0.72 Å. The Y(1)-P(2) bond length is 0.17 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in an L-shaped geometry to one Ca(1) and one Y(1) atom. In the second P site, P(2) is bonded in an L-shaped geometry to one Ca(1) and one Y(1) atom.
