SrGaP2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrGaP2 clusters. Sr(1) is bonded in a single-bond geometry to one Ga(1), one P(1), and one P(2) atom. The Sr(1)-Ga(1) bond length is 0.40 Å. The Sr(1)-P(1) bond length is 0.29 Å. The Sr(1)-P(2) bond length is 0.26 Å. Ga(1) is bonded in a 2-coordinate geometry to one Sr(1) and one P(2) atom. The Ga(1)-P(2) bond length is 0.48 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second P site, P(2) is bonded in a single-bond geometry to one Sr(1) and one Ga(1) atom.
