The material described by Sr3P2 crystallizes in the tetragonal I-42d space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to one P(1), two equivalent P(2), and two equivalent P(3) atoms. In the second Sr site, Sr(2) is bonded in a 5-coordinate geometry to one P(2), two equivalent P(1), and two equivalent P(3) atoms. In the third Sr site, Sr(3) is bonded in a 5-coordinate geometry to one P(1), one P(2), and three equivalent P(3) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent Sr(3), and four equivalent Sr(2) atoms. In the second P site, P(2) is bonded in a 8-coordinate geometry to two equivalent Sr(2), two equivalent Sr(3), and four equivalent Sr(1) atoms. In the third P site, P(3) is bonded in a 7-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and three equivalent Sr(3) atoms. is represented by the CIF card [CIF]
