Materials Data on P(HO)3 by Materials Project
H3PO3 crystallizes in the monoclinic P2_1 space group. The structure is one-dimensional and consists of six phosphorous acid molecules and one H3PO3 ribbon oriented in the (0, 1, 0) direction. In the H3PO3 ribbon, P5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of P–O bond distances ranging from 1.62–1.66 Å. There are three inequivalent H+0.33+ sites. In the first H+0.33+ site, H+0.33+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H+0.33+ site, H+0.33+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.70 Å) H–O bond length. In the third H+0.33+ site, H+0.33+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H+0.33+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one H+0.33+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one P5+ and two H+0.33+ atoms.
