Materials Data on P2S2O3 by Materials Project
P2S2O3 is alpha Po structured and crystallizes in the tetragonal I-4c2 space group. The structure is zero-dimensional and consists of four P2S2O3 clusters. P5+ is bonded to one S2- and three O2- atoms to form distorted corner-sharing PSO3 tetrahedra. The P–S bond length is 1.87 Å. All P–O bond lengths are 1.64 Å. S2- is bonded in a single-bond geometry to one P5+ atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms.
