The structure described by SrP2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 9-coordinate geometry to three equivalent P(1), three equivalent P(2), and three equivalent P(3) atoms. In the second Sr site, Sr(2) is bonded to two equivalent P(1), two equivalent P(2), and two equivalent P(3) atoms to form SrP6 octahedra that share corners with four equivalent P(3)Sr4P2 octahedra. The corner-sharing octahedral tilt angles range from 33-75°. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 6-coordinate geometry to one Sr(2), three equivalent Sr(1), one P(2), and one P(3) atom. In the second P site, P(2) is bonded in a 6-coordinate geometry to one Sr(2), three equivalent Sr(1), one P(1), and one P(3) atom. In the third P site, P(3) is bonded to one Sr(2), three equivalent Sr(1), one P(1), and one P(2) atom to form distorted PSr4P2 octahedra that share corners with two equivalent Sr(2)P6 octahedra and corners with seven equivalent P(3)Sr4P2 octahedra. The corner-sharing octahedral tilt angles range from 0-102°. is represented by the CIF card [CIF]
