Materials Data on ThP2H2CO8 by Materials Project

Th(PO3)2CH2O2 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional and consists of four hydrogen peroxide;methane molecules and one Th(PO3)2 framework. In the Th(PO3)2 framework, Th4+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Th–O bond distances ranging from 2.28–2.37 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. All P–O bond lengths are 1.54 Å. In the second P5+ site, P5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.54 Å) and two longer (1.55 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Th4+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to one Th4+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Th4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Th4+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Th4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted linear geometry to one Th4+ and one P5+ atom.
