SrP3 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 7-coordinate geometry to one P(1) and eight equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one Sr(1), one P(1), and two equivalent P(2) atoms. In the second P site, P(2) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one P(1), and one P(2) atom.
SrP3 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 7-coordinate geometry to one P(1) and eight equivalent P(2) atoms. The Sr(1)-P(1) bond length is 3.25 Å. There are a spread of Sr(1)-P(2) bond distances ranging from 3.04-3.50 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one Sr(1), one P(1), and two equivalent P(2) atoms. The P(1)-P(1) bond length is 2.26 Å. Both P(1)-P(2) bond lengths are 2.19 Å. In the second P site, P(2) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one P(1), and one P(2) atom. The P(2)-P(2) bond length is 2.23 Å.
