Materials Data on Sn2P2O7 by Materials Project
Sn2P2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sn2+ sites. In the first Sn2+ site, Sn2+ is bonded to five O2- atoms to form distorted SnO5 square pyramids that share corners with five PO4 tetrahedra and edges with two equivalent SnO5 square pyramids. There are a spread of Sn–O bond distances ranging from 2.25–2.68 Å. In the second Sn2+ site, Sn2+ is bonded to five O2- atoms to form distorted SnO5 square pyramids that share corners with five PO4 tetrahedra and edges with two equivalent SnO5 square pyramids. There are a spread of Sn–O bond distances ranging from 2.26–2.66 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six SnO5 square pyramids and a cornercorner with one PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four SnO5 square pyramids and a cornercorner with one PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.52–1.65 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two Sn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Sn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Sn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Sn2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sn2+ and one P5+ atom.
