Materials Data on SiP2O7 by Materials Project
Abstract
SiP2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Si4+ is bonded to six O2- atoms to form SiO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.76–1.84 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent SiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 9–48°. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Si4+ and one P5+ atom. In the second O2- site, O2- is bonded in a linear geometry to one Si4+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Si4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent P5+ atoms.
