SrP is alpha boron-derived structured and crystallizes in the hexagonal P-62m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(2) is bonded to three equivalent Sr(1), three equivalent Sr(2), and one P(2) atom to form a mixture of distorted face, corner, and edge-sharing PSr6P pentagonal bipyramids. In the second P site, P(1) is bonded to three equivalent Sr(1), three equivalent Sr(2), and one P(1) atom to form a mixture of distorted face, corner, and edge-sharing PSr6P pentagonal bipyramids.

In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. Both Sr(1)-P(2) bond lengths are 3.12 Å. All Sr(1)-P(1) bond lengths are 3.20 Å. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. Both Sr(2)-P(2) bond lengths are 3.11 Å. All Sr(2)-P(1) bond lengths are 3.04 Å. There are two inequivalent P sites. In the first P site, P(2) is bonded to three equivalent Sr(1), three equivalent Sr(2), and one P(2) atom to form a mixture of distorted face, corner, and edge-sharing PSr6P pentagonal bipyramids. The P(2)-P(2) bond length is 2.25 Å. In the second P site, P(1) is bonded to three equivalent Sr(1), three equivalent Sr(2), and one P(1) atom to form a mixture of distorted face, corner, and edge-sharing PSr6P pentagonal bipyramids. The P(1)-P(1) bond length is 2.31 Å.
