SrP2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine P1- atoms. There are a spread of Sr–P bond distances ranging from 3.16–3.44 Å. In the second Sr2+ site, Sr2+ is bonded to six P1- atoms to form SrP6 octahedra that share corners with four equivalent PSr4P2 octahedra. The corner-sharing octahedra tilt angles range from 32–77°. There are a spread of Sr–P bond distances ranging from 3.07–3.09 Å. There are three inequivalent P1- sites. In the first P1- site, P1- is bonded in a 6-coordinate geometry to four Sr2+ and two P1- atoms. There are one shorter (2.21 Å) and one longer (2.25 Å) P–P bond lengths. In the second P1- site, P1- is bonded in a 6-coordinate geometry to four Sr2+ and two P1- atoms. The P–P bond length is 2.22 Å. In the third P1- site, P1- is bonded to four Sr2+ and two P1- atoms to form distorted PSr4P2 octahedra that share corners with two equivalent SrP6 octahedra and corners with seven equivalent PSr4P2 octahedra. The corner-sharing octahedra tilt angles range from 0–102°.
