Materials Data on PH5CO3 by Materials Project
CPH5O3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two CPH5O3 sheets oriented in the (0, 0, 1) direction. C4- is bonded in a distorted tetrahedral geometry to one P5+ and three H1+ atoms. The C–P bond length is 1.78 Å. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. P5+ is bonded in a tetrahedral geometry to one C4- and three O2- atoms. There is one shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.54 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.51 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one P5+ and two H1+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom.
