SrP2(H2O3)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.51–2.78 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a distorted tetrahedral geometry to one H and three O2- atoms. The P–H bond length is 1.41 Å. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. In the second P5+ site, P5+ is bonded in a distorted tetrahedral geometry to one H and three O2- atoms. The P–H bond length is 1.41 Å. There is two shorter (1.52 Å) and one longer (1.61 Å) P–O bond length. There are four inequivalent H sites. In the first H site, H is bonded in a linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.70 Å) H–O bond length. In the second H site, H is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.79 Å) H–O bond length. In the third H site, H is bonded in a single-bond geometry to one P5+ atom. In the fourth H site, H is bonded in a single-bond geometry to one P5+ atom. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sr2+, one P5+, and one H atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, one P5+, and two H atoms. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+ and one P5+ atom.
